The best personal training facility in Portsmouth.

I joined Constant Fitness a month ago, and it’s one of the best decisions I’ve made! The gym has a fantastic atmosphere, clean, well-equipped, and welcoming to people of all fitness levels. The staff ( Sam, JJ & Lenny) are incredibly friendly and knowledgeable, always ready to offer guidance or encouragement. Whether it’s the variety of classes, the top-notch equipment, or the personalized approach, everything is designed to help you. I’ve already noticed a positive change in my lifestyle, and I look forward to every session. Highly recommend Constant Fitness to anyone looking for a supportive and professional gym in Portsmouth!

Love going to Constant Fitness!! I'm only at the start of my journey but Sam has been a great support and given me all the advice and guidance I need to progress. The SGPT sessions are great; for someone like me who doesn't like a busy environment these are perfect and capped at 8 people per session. Also big shout out to Lenny and JJ for your support too - couldn't have bagged some PB's without you all cheerleading me on. Can't wait to continue and I highly recommend Constant Fitness to everyone no matter where you are on your fitness journey 💪🏻❤️

I started training with Constance Fitness two months ago, after seeing the incredible impact it had on my husband, who began training with them five months earlier. His transformation motivated me to join this amazing team. This was my first time going to the gym and working out, and while I was really excited, I was also a bit nervous. As a full-time nurse and a mom of a toddler, I was worried about how much I could commit to my fitness journey. I realized I needed consistent motivation and guidance, and that’s exactly what Sam, Lenny, and JJ provided. They are amazing coaches who taught me everything from the basics of working out to planning my sessions and making healthier choices with snacks and grocery shopping. Their support has had a huge impact on our family’s nutrition and, of course, the results I’ve seen. In just two months, I feel so much more energetic and active than I used to be. I’ve noticed a significant improvement in my leg cramps and overall strength. Thank you so much, Constance Fitness team, for the incredible support and encouragement over these past two months. I’m excited to continue this journey!

I joined Constant Fitness back in June 2024. I have never properly exercised before (!) as always ended up with an injury or got bored. Since joining Constant Fitness, exercise is now a must for me each week. I thought that training in a small group would be weird or intimidating, but it’s not. The support and encouragement from everyone is amazing and now I wouldn’t want to solo train. The structure of the sessions combined with help and guidance from Sam, Lenny and JJ (either from coach catch-ups or during classes) have made me stronger than I’ve ever been before - Thank you. I’m excited to see where I can go from here.

I have been a member at constant for 1 month. From the moment I met Sam & JJ, I knew they were going to be a great fit. The way they picked up my imbalances instantly & gave feedback with corrections just proves to me how much they understand bodies & can tailor to each individual. Despite being up to 8 people being coached at any one time, you still get the 1-2-1 dedication. They are both attentive in their own ways & truly care about all their members. They are constantly checking in, giving advice & adapting to your needs on the day. As I’ve only been here 1 month I can’t comment on progression with compound lifts or scale numbers but I’m just settling in and sure they will come in time.

I’ve never been an active person since my early 20s, despite enjoying sports and being a good cricketer. As I began working in the IT sector, my physical activity gradually declined, and I unknowingly fell into a sedentary lifestyle. My wife and I often planned to start a simple routine, like walking, but we struggled to maintain it, especially after having our daughter. That’s when I decided to try personal training, knowing I needed someone to motivate and guide me through the process. Joining Constant Fitness has been one of the best decisions I’ve made. I had no idea how many calories I was consuming daily or why my energy levels were so low. Sam has been incredibly helpful, particularly in teaching me about nutrition and calories. With Sam, JJ, and Lenny personalizing my workouts, I’ve been able to achieve goals I once thought were out of reach. I’m deeply grateful for the amazing training environment they’ve created. At no point did I ever feel awkward, shy, or uncomfortable. They’ve truly built something spacial, and I thank them from the bottom of my heart.

The most amazing gym you could possibly imagine, the support you have from the team is insane, the atmosphere is brilliant and plus the things you learn about health and nutrition through out the support is brilliant!

I have constantly been on and off with the gym and have always struggled to commit to it. Since joining constant fitness in April 2024 I have found the motivation and confidence to improve my fitness journey and stick with it! Constant is unlike any other gym I have been to before. Every class and session is great and really enjoyable, the PTs know how to get the best out of you and can accommodate any goals. The atmosphere is unmatched. The community and team makes every session a fun challenge. Before I wouldn’t imagine going to the gym at 6am, now I look forward to it. Sam, JJ & Lenny have made a community where everyone is welcome and everyone wants to be there. I have seen massive improvements in my strength and general fitness and I wouldn’t have been able to do it without Constant!

It's an incredible experience training at Constant. The team is super friendly and welcoming; always greeting you with a smile and ready for...training! The Constant team is very knowledgeable and within a supportive environment, they provide small group PT, structured workouts suitable for all abilities. Highly recommend it for people who prefer a structured workout session, or are slightly nervous about going to a commercial gym. Before joining Constant Fitness, I reached a plateau stage and started to lose motivation as I was struggling to see any progress in my fitness journey. I initially signed up for the 30-day no-commitment trial. Since then, I have enjoyed my workouts so much that I am continuing my membership as I noticed the progress and wanted to keep it up. And now, just after 4 months, I can wholeheartedly say that I am so glad I found this place and regret not finding it any sooner!

I joined Constant fitness because I’d fallen out of love with the gym, lost all motivation but really missed the feeling after a great workout. I now get that feeling guaranteed after every session, all I have to do is turn up and work hard.
