The HIIT Locker: Opinions

Fantastic experience: Before starting with The HIIT Locker I considered myself fit enough, but was starting to carry a few extra pounds and knew that my joints were struggling with a lack of any strength and conditioning work. I immediately LOVED the sessions -perfect length of time, varied exercises, clear direction and encouragement from all the trainers. The nutrition programme just helped me focus on the things I already knew and gave me extra tips to see it through with accountability too. I have lost weight, lost body fat and visceral fat. I am MUCH stronger overall, and also much more confident with the weaker joints that I have, to do the exercises we’re given. I’m fitter and more confident to try new exercises and even jobs round the house. I have recommended it to anyone I know interested in changing their mindset and health! For all the benefits of the sessions and programme, it’s the friendliness and atmosphere that really makes The HIIT Locker stand out.

Fantastic experience: Before starting with The HIIT Locker I felt sluggish kind of stuck in a rut, tired, no energy, putting on weight and doing nothing. Training sessions at the start were brutal lol & it was great to have a nutrition coach to help with any problem I had with recording & keeping me on track, coaches are amazing to work with, very friendly, very professional and a great wee team of coaches It took me 2yrs before any weight started to shift (for some reason), I find myself more energetic, clothes are fitting better & slowly I'm getting stronger & stronger. I would recommend The HIIT Locker, Great coaches who go out of their way to help you, small group's when training, good atmosphere, friendly staff and in a great location!

Fantastic experience: Before starting with The HIIT Locker I found myself Just sitting in the house every day, not doing any exercise, eating chocolate at the weekend. Board no confidence life just passing me by. Getting bigger fooling myself that I was fine. Energy very low. Love the training sessions, the guys are brilliant there and helped me get where am today. I have more confidence and energy, just love the banter. I have dropped 2 sizes, my fitness has improved so much, have more energy. I feel great getting into smaller clothes and shoes. It's a brilliant gym nobody cares what you wear or what size you are, that's want you want, no criticism just encouragement and people who understand what you are here for. It's something for you to enjoy the banter, to feel good about yourself and make friends.

Fantastic experience: Before starting the programme at The HIIT Locker I felt very out of shape, I found myself unable to do simple tasks I used to not think about and I was ill all the time. The programme is very simple but it provides amazing results very quickly. The staff are very welcoming and can help with any problems. I have noticed that my body is changing and my energy levels are back to what they were before, I can fit more comfortably into my clothes and have ended up sizing down and friends and family have noticed I’m much happier. I speak very highly of The HIIT Locker and recommend it any chance I get.

Fantastic experience: Posting on behalf of my husband, who has been going for the last 6 months. The HIIT Locker experience. I attended the HIIT Locker because I had become overweight, unfit and was uncomfortable in my own skin. I found physical tasks were taking longer to complete, leaving me feeling sore afterwards and having a negative effect on my confidence. Initially I joined the gym to partake in the 8 week HIIT programme. I had never taken formal classes before and wasn't sure what to expect. I found the coaches were very personable, knowledgable and good at putting people at ease, offering guidance about techniques, adjustments and alternative exercises where applicable. They also offered excellent advice and assistance through the nutrition programme. After the first few weeks of the programme I began to see some physical benefits, a bit of weight loss, improved energy levels and a mood of positivity. After the initial 8 week programme I changed my routine to doing interval weight training twice and HIIT class once per week. This has been great for me, I feel fitter, stronger and generally healthier. Physical tasks that I previously found difficult are now not so daunting, I now have more stamina. Family and friends have noticed and have commented on a significant difference in my shape and demeanour. Old clothes are much looser or ill fitting, new clothes are a size or two smaller. Attending the HIIT Locker has had a really positive impact on my physical and mental health, making me more confident and comfortable in myself.

Fantastic experience: When I joined The HIIT Locker I was running two or three times a week but wanted to build some strength and muscle mass. I was looking to have something more than just the cardio I was doing with the running. The HIIT Locker team is great. I felt very comfortable from the beginning. Everyone knows what they are doing and all the sessions have a friendly atmosphere. For me, the programme was just what I needed with intense training session in a short period of time. I’ve had very good results from start. I gained strength and improved my muscle tone and that helped me not get fatigued after my long runs. I also feel better, I sleep better and the training sessions help to manage my stress levels also. I would absolutely recommend the HIIT Locker!

Fantastic experience: I had gone through breast cancer treatment, in 2021, before I started The HIIT locker and the medication resulted in me gaining weight and having chronic fatigue. I saw the adverts online and knew I needed to do something so I did the 6 week programme with Andrew as my nutrition coach. Andrew was so helpful and guided me to hit my nutrition targets. I still use MyFitnessPal daily to stay on track. When I started in July 2022 I was 168 pounds and I'm not sure what I lost in the 6 weeks but it was enough for me to sign up long term. Fast forward 1 year and I'm down to 140 pounds with my body fat levels and BMI both reduced. I'm not entirely sure of those figures but I'm now back in size 10 clothes and when I started I was a size 14-16. I have more energy and feel so much more confident in my own skin. My kids and family have all noticed the positive changes in me. A couple of my friends have joined The HIIT Locker as they saw the proof that it works, with my results. It's the only thing I've consistently stuck at as I love the whole environment. The coaches, and members alike, all encourage each other. It's just fab. I have encouraged so many people to join.

Fantastic experience: Before I started at The HIIT Locker I was slowly but steadily putting weight on, even with an active job ( around food mind ), showing itself as a noticeable rounded stomach ... I also had constant aching in my leg, my fitness levels were also pretty poor I discovered regardless of the aforementioned active working day. My random surfing that in previous years was much more constant began to suffer when I had the opportunity so I guess this was the driving factor in signing up. The very simple to follow HiiT classes along with the trainer's help, advice and encouragement was and is second to none, a brilliant bunch of people! My energy levels have lifted and I actively look forward to sessions, I've lost over a stone in weight and muscle definition is a nice side effect, along with the pot belly losing the will to stick about, I've also dropped two waist sizes , my wife, friends and family have all commented on how well I'm looking. One of the biggest positives is no longer being utterly destroyed after a surf session not to mention being able to catch more wave I would have no hesitation in recommending The HIIT Locker for anyone looking to improve their fitness levels.

Fantastic experience: I joined up after having my daughter, I had tried to lose the weight through a weight loss plan but it wasn't shifting. At the time I had moved house and didn't have the confidence to join a new gym without getting my weight off but then I seen The HIIT Locker and it looked exactly what I needed. I joined in December 2017 so I've been here for over 5 years now. This is the first time I've loved going to the gym and look forward to my sessions. Honestly, the nutrition side took me a while to get the hang of it especially with the protein. But the coaches are very patient and help you. You get a weekly call which is so useful and any questions you have get answered. The coach also looks at your food diary and how many times you've trained. You then get a plan for the following week. Once you crack the protein you're flying and it also keeps you filled up in between meals. This isn't a diet its just a healthy way of life as no food is off limit. If you do have a treat or night out you just cut down the next few days. The coaches are always so supportive and easy to get along with. Some of the exercises are different from what I had done in the past but the coaches are right there fixing your form and giving you tips. I really enjoy the training sessions and the other members are like a community. Everyone gets excited and cheers you on when you reach your goals but also if you need extra help the members are always there with great suggestions. We have a closed Facebook page which is a great help for tips or if you're struggling or need some recipe ideas. Since joining honestly my weight has been up and down but the coaches have been right there helping and encouraging me. I feel great and healthy on the inside and out.

Fantastic experience: Before I got started with The HIIT Locker my fitness was not good and my BMI said I was obese which affected my confidence. I didn’t feel strong, I wasn’t happy with how I looked and I was worried about my health. When I got started with the programme I really enjoyed how interactive it was in that everyone doing exercise together helped motivate me. All the coaches were friendly, accommodating of my needs and encouraged me to push myself which I would struggle to do if I was going to just a normal gym. Results wise, I have lost weight and body fat. I can now fit into my old size 10 skinny jeans. From family to friends and neighbours everyone has commented on the weight I’ve lost and I’ve been told I’m glowing. Even my ex partner told me I inspired him to go to lift again I would highly recommend The HIIT Locker - thank you!

Fantastic experience: Before joining The Home HIIT Project I was in a complete rut. Having 2 small kids, juggling a full time job working from home, I was just lost. Not eating right, and if I was, I was binge eating. Always making sure my husband and kids were looked after and not looking after myself. Had mastered the art of maintaining my unhealthly weight. Having recently had some bad news from a genetic testing result, having come to terms with it I realised I had to get my act together but knew I couldn’t do it myself and lacked the confidence to go to local gyms and needed something to help me get back on the straight and narrow and most importantly work with my work and family life. The coaches just make everything simple and straightforward. I knew very little about a calorie deficit and how it worked. But it does! I’m amazed at how much I have to eat and how this has already just 4 weeks in has totally changed my habits and mindset. I find myself more knowledgable on what to eat and not what to eat and how to manage calorie intake on a daily basis so if there’s something I want, I can have it. The whole MyFitnessPal is dead easy, actually kind of become a healthy obsession! I do the early morning sessions with Phil, lots of encouragement, and modifies it accordingly. So totally suitable for every type of fitness level. And also have access to the members page with access to set workouts if I want to do anything extra ☺️ 4 weeks in, slow and steady progress and enough to make me realise I’m finally achieving what I want to achieve and am proud of myself. Body shape has changed already in just 4 WEEKS! Most importantly for me personally it’s the staff. From day one the support is fantastic, they actually care and want to help. And they are just a text away. To have someone to be accountable to, that’s what makes this work for me. And my achievements ultimately help me massively in what I want and at the same time help get the word out about how awesome and genuine these guys are ❤️Achieving my goals will be thanks to them. And once my programme ends I will most definitely will be continuing my journey with The Home HIIT project. The comfort I get from them all, I wouldn’t want to do it with anyone else

Fantastic experience: When I joined The HIIT Locker towards the end of August, I weighed a little under 15 stone (having put 10lbs back on in a couple of months through birthdays, barbeques and my 20th Wedding Anniversary). I used to be a competitive fencer but through a combination of factors I was now seriously unfit, significantly overweight and generally unhappy with myself. I was always absolutely shattered every morning and had no energy or drive to do anything. My clothes didn't fit well, or getting bigger and bigger sizes and I had zero muscle tone or strength. I couldn't even do 5 press ups. I'd also never trained using weights before so The HIIT Locker was a novel, if painful, experience to start with, as my muscles and body became used to strenuous exercise again. I found the nutrition app and coaching really useful and quite straightforward, albeit a bit of a shock when you see the calorie content of what you're eating! What's really great about the programme is the small group aspect. Whether with the nutrition or sessions there's always a personal touch and all the coaches are really good at pushing you on without making you feel incapable. The atmosphere in the sessions is always fun and there's a good bit of banter, and support, from everyone. I definitely feel part of a group, not just a faceless body in the crowd. In the 11 weeks I've been there I've lost over 1 stone and I fit clothes I bought years ago but could never wear without feeling self-conscious. I've noticed how quickly my strength and endurance levels picked up and the weights I can work with have increased steadily. I'm much fitter, healthier, definitely skinnier and happier than I've been in years. Perhaps one of the most telling things was walking in to class and Shan exclaiming 'You're so lean!', having not seen me for a couple of weeks. It doesn't get easier because you push onwards, heavier weights, more reps, faster tempo, but it's certainly made a difference to me. Well worth the time, effort and money. It feels like another family.

Fantastic experience: Before I got started at The HIIT Locker I’d been away from training for over a decade. I was a stone overweight, lethargic and extremely unconfident. The programme’s great. Due to injury I was, and still am, only able to do the interval weight training sessions but you get out what you put in. I’ve been unlucky and had Andrew every session (haha!). He’s great, keeps tweaking exercises & adding that little extra bit of weight to push me further. My results are fantastic. I’m now lighter, leaner, stronger and a lot more confident. Had to buy a new wardrobe, probably about time!

ciara mc guirk 2 years ago

Fantastic experience: Before starting the HIIT locker I was out of shape, aching joints, had low energy, poor flexibility, little strength. I Found the start daunting, I was so uncoordinated and unfit, but the trainers were so helpful and friendly I soon started enjoying the classes and really looking forward to it. In 11 months I have lost nearly 2 stone but the best thing is how much fitter and stronger I have become and how much I enjoy exercise. It has helped me realise that exercise is the best medicine for staying young no matter what age you are.

Jim Parker 2 years ago

Fantastic experience: Before I started at The HIIT Locker my diet was very unhealthy. Lots of snacks and too many carry outs. My exercise regime would consist of a leisurely stroll with the dog every day and little else. Previous resolutions to get fit would rarely last more than 3 days. My weight had began to creep up over the years and before I started The HIIT Locker I was really struggling to get into some 36 inch waist trousers and would wear XL shirts. Consequently my self confidence would have been fairly low, I’d avoid looking at myself in mirrors where possible and I’d hate photos of myself. I came to The HIIT Locker through an ad on Facebook. I’d had a bit of a mild health scare and with my family having a long history of heart problems I decided it was time to do something about it. I was given the hard sell (lol) by Emma over the phone and she explained the whole plan in a very non-daunting way while Phil’s nutrition tutorial videos were really informative and well presented. The first training session I was very apprehensive but the trainers were really supportive and eased me through it and I soon realised nearly everyone else had been just as nervous on their first day. I can’t say enough about the trainers. Their good nature, enthusiasm and knowledge is second to none. Every session strikes a balance between craic and hard work. They make time for everyone in the sessions and are always there with helpful coaching cues and pointers. I was lucky to get Hugh as my nutrition coach. The first few of the weekly calls were particularly important for me as changing my diet was definitely the most challenging aspect of the programme for me. Hugh worked with me on a one-on-one basis until we found which daily calorie and protein intake worked best for me and he would keep me on the straight and narrow with his cajoling and encouragement. I’ve had some great results with the programme and I’m probably in the best shape of my life. I’ve dropped over 3.5 stone, my body fat percentage has more than halved and I’ve basically had to buy almost a whole new wardrobe as none of my old clothes fit me. 32 inch trouser waists are now a little baggy on me and I can fit into some medium size shirts. People who hadn’t seen me for a while were really surprised and shocked by my appearance. I’ve definitely got much more energy and confidence than before. I’d heartily recommend The HIIT Locker to everyone.

Fantastic experience: Before I joined The HIIT Locker I was just dieting. I’d lost some weight but hit a bit of a plateau for a couple of months which was de-motivating. I wasn’t fit at all, was in a gym but didn’t really know what I was doing. I thought The HIIT Locker would get me back on track to my weight loss goal and it did. When I started I really enjoyed the programme. It was great going in a few times a week and learning new exercises and always trying something new every training session. Even today the trainers still throw stuff into the workouts that I’ve never done before. The trainers were very supportive and really helped me with my nutrition, something I always struggled with. I also find they are very motivational, they push you to get an extra few reps in at the end of a set, when they know you can do it. I honestly don’t have a bad word to say about any of the trainers at the gym. I’ve found recently my clothes are too big for me now, which I see as a good problem. I’m also a lot more toned, I feel, and still have more to accomplish. I feel posture was always something I struggled with, and have noticed my posture has gotten a lot better, especially with the back exercises I have done. I receive a lot of compliments from friends and family about how much weight I’ve lost, and when new people I meet see old photos of me they can’t believe how much I’ve changed. I’ve also found my confidence has improved massively.

Fantastic experience: Before I started at The HIIT Locker I was the heaviest I’ve ever been in my life. I have fibromyalgia and I felt tired all the time, out of shape, out of breath. I was so fed up with how I looked and I just didn’t know what to do anymore. When I got started, I had no idea what to expect and went in with an open mind and open to help. Everyone was super welcoming and understanding. The programme is brilliant and teaches me how to incorporate life into my nutrition. I’ve lost a stone so far, and I have got a plateau. But I’m keeping doing the things I need to. My clothes fit so much better and people have commented but more important is that even though I still have fibromyalgia flare ups, I have the stamina to push through them more, now. I’m able to go for longer walks, I enjoy my HIIT sessions and just feel so much better inside and out. For me learning about proper nutrition has been key. I don’t feel deprived of anything, and I’m motivated to push myself to do better in the HIIT sessions as well.
