I was a member of One Element Tooting for 3 years. I loved being part of the group and saw my fitness really improve over this time. The mix of HIIT, circuits and kettle bell classes never got boring or repetitive. I made some amazing friends and benefitted from being part of a supportive local community. I recommend this group to all ages and fitness levels and am sad to have moved away from the area.
I joined One Element Tooting at the end of lockdown and it’s been such a brilliant fitness group to be part of. Social, fun, and great trainers who give positive encouragement to help you reach your fitness goals - no shouting! Thank you for the fun, fitness, friendship and fond memories.
Response from the owner:Thanks Lucy for being part of the community and always bringing positive energy to the group. Enjoy your new life by the sea.
I've only been attending classes for a few months but already noticed an improvement in my fitness. Despite the cold weather there's always a good turnout and a great community spirit
Response from the owner:Thanks Emily. So good to have you as part of our community.
This is a phenomenal class! Fitness in the park and not even the park run group intimidates us. I needed motivation to start my fitness journey and I couldn't run for the life of me! Now that’s all changed. I am part of a tribe that strives for better with many being part of the group for 10+years etc. the motivational messages from the coaches is absolutely helpful and progress is tracked! I was surprised when I was told I was most improved of the class recently in a session!It pays off! Join the tribe!
Response from the owner:Thanks for such a lovely review Leila. It's fantastic to see your progress. Keep going 🙂
I’ve been going to OE in Tooting since 2022 and I love it! If someone had told me a few years ago I’d do exercise outside in the middle of winter, I’d have laughed at them! The sessions are great and all the people at OE are so lovely and supportive.
Response from the owner:Thanks Alex. We love having you has part of the group 🙌
Excellent bootcamp with lots of options to choose between Monday and Saturday. Everyone is friendly and ready to challenge you. Nothing better than training with friends in a beautiful park! And the socials are great too 🙂
One Element has improved my life physically and mentally. It is incredible to be exercising in direct contact with nature. Tom, beyond knowledge, transmits an energy that is beyond words to describe. Long live One Element.
I can't speak highly enough of One Element, expertly led by Tom. I joined 6 years ago and have been a regular member since, attending their numerous park based training sessions where I have considerably improved my strength and fitness and general wellbeing. If you are looking for a social, positive, outdoor training class look no further!
I joined One Element in 2021 following the pandemic, and I have to say it’s been a game-changer for both my fitness and social life! The workouts are held in parks, surrounded by nature, which makes every session feel more like an adventure than a routine exercise. The variety of exercises keeps it exciting, from high-intensity interval training to strength-building circuits, and there's always something new to challenge me. What I love most is the sense of community. I've met so many like-minded people who are also focused on staying fit, and it’s been awesome to build friendships through shared goals. The group has a very welcoming atmosphere, and the trainers are always supportive, ensuring that everyone can go at their own pace while pushing themselves to improve. If you’re looking for a fun way to stay in shape and meet new friends, I highly recommend giving it a try!
I felt I’d found gold dust when I started at One Element in 2018 and have loved it ever since. The sessions are wonderfully varied and Tom strikes the perfect balance tolerating us chatting and laughing, but then encourages us to work so hard we each leave feeling very pleased with ourselves. Outdoor fitness is the best - we train in frost mud and sun and enjoy the changing seasons. You don’t need any kit so why don’t you come to a trial session and see what we all rave about.
I couldn’t recommend One Element more. I recently rejoined after a few years away having children and it couldn’t be a more welcoming and friendly exercise experience. Tom is full of motivation and has so much positive energy that rubs off onto everyone there. I always come away feeling lighter, energised, happy, a little sore and very muddy!
Response from the owner:Thank you Jess. I really appreciate this.
I would highly recommend One Element, the workouts are amazing, well thought out and the trainers are fantastic. I exercise in Wandsworth Park which is probably the best venue ever. One Element also offers a wide range of online and on demand content which is great for when you can’t get to the park.
Ive been coming to one element for 4+ years and I love it. My fitness has dramatically improved and I feel better and stronger than I ever have. The euphoria of doing this all outside, amongst friends, in any condition cannot be beaten. Tom is fantastic—always motivating, knowledgeable, and ready to push you to achieve your best while making every session fun and engaging. No two workouts are ever the same, keeping things fresh and challenging. Whether it’s rain, shine, or even snow, the energy and camaraderie make it all worthwhile. I can’t recommend One Element enough for anyone looking to improve their fitness in a supportive and uplifting environment!
Great group. A lot of sessions available from Monday to Saturday. I like the variety and exercising outdoors. The people and coaches from this bootcamp are very friendly and committed. They have never cancelled a session since I joined 2 years ago.
One Element fitness sessions are the best. I’ve been doing it for about a year. You just need to turn up. Trainers are great, everyone is welcoming and there’s people of all different abilities, you always push yourself and leave feeling great.
I joined One Element nearly four years ago now during Covid and it is one of the best things I have done. I hated going to the gym and motivating myself to get up at home and do some sort of weights/fitness was never going to work! I joined OE with a friend and we have been going almost faithfully twice a week since. My fitness levels have improved, I have taken on a new desire to run and it is good fun. Training outside is exhilarating and although the weather can be challenging at times, by the end of the session you always feel better and glad that you made the effort to come along. I would highly recommend to anyone who wants to improve their fitness level in a fun and friendly environment.
One element is amazing- exercising outdoors with a lovely, friendly group of people and talented knowledgeable instructors . Fantastic way to start day. It makes you want to exercise which is a good start!!! We all know how hard it is to be consistent with exercise but one element makes it much easier !
I joined One Element Tooting last August and have noticeably seen the benefits! As someone who enjoyed exercising on their own at their own pace but struggled to motivate myself into a routine, my perception of exercise has completely changed. I now look forward to exercising and noticeably miss my One Element classes when I can’t go! One Element challenges me each week while being cheered on by friendly people, it’s inclusive to all fitness abilities and I feel so much better and healthier for working out outside. Each session is different, meaning I am always being challenged and it keeps it fun! I have noticeably seen the difference in my fitness capabilities outside of One Element too. The social side is fantastic, with the owner Rich regularly planning a range of activities and events. Everyone is so friendly and welcoming.
Response from the owner:Thanks for the great review Anna. So good having you part of the community.
I've been a member at various locations for the last 3/4 years and love it. Rain or shine a sociable workout outdoors will always trump going to a gym!
Response from the owner:Thanks for the review Roman!
This is me right at the end of completing the three peaks challenge, something I would have really suffered doing before joining One Element. The mix of cardio and strength training is great for functional fitness and the team is hugely welcoming and supportive. And even in the worst of the outdoor weather, it’s much more pleasant than at the top of those mountains!
Response from the owner:Amazing achievement Beth. Thanks for the review and great to have you part of our community.
I have loved working out outdoors this summer, an amazing change to indoor gyms. I would highly recommend One Element Tooting! Thanks to all the amazing trainers who make the sessions both enjoyable and challenging 🌟
Response from the owner:Thanks for the review Rachael. So glad you're enjoying being part of our community.
I don’t think I can ever put into words how much One Element means to me. It sounds soppy but after the pandemic, being shut inside and talking to no one, this was one of the best things I did. Everyone is so incredibly friendly and encouraging and being honest, although I joined for the social side, I’ve seen a huge improvement in my fitness and even worked up to doing a tough mudder! I couldn’t recommend OE enough to anyone wanting to make friends or just get out and be active. The holidays are also immense, the surf trip has been a particular highlight! I’m sad to have to leave but I’ve made some great friends and I will definitely be back one day! X
Response from the owner:Thanks Lauren - it's been awesome having you as part of the group. Enjoy your travels and see you when you're back!
Amazing atmosphere, fun (and intense) workout with great people who really motivate each other to get off the sofa! Highly recommended!
Response from the owner:Thanks Priamo - brilliant to hear!
Joined One Element at Tooting in the summer and it's been a total game changer. Have never previously managed to get into & enjoy regular exercise but OE has me out two to three times a week. A great combo of fun / varied sessions, lovely group of people & trainers and just great to be out in the outdoors - even in the cold snap! Highly recommend.
Response from the owner:Thanks Claire - so great to hear this!
I joined One-Element in the summer and my fitness level has improved tremendously. The sessions are fun and challenging. The session enables you to build your fitness level at your own pace. Rich also organises some really good social 🙂 highly recommended
Response from the owner:Thanks Sachin! Great to have you part of the group.
