Trustindex verifies that the original source of the review is Google. 3 years ago I limped into Athlon, crippled with a slipped disc, sciatica and 3 stone heavier. Having been told that I should never lift anything heavier than a wine glass, Dave from Athlon was having none of it. My fitness levels through weight training has transformed my life. For someone who ‘didn’t do gyms,’ I can’t thank Dave Perry enough for how much he’s helped me. Athlon are the real deal, a gym that all people of all ages can benefit from.Posted on wendy harrisonTrustindex verifies that the original source of the review is Google. A really welcoming and friendly gym. The daily classes and trainers are brilliant. Highly recommend!Posted on asher whitingTrustindex verifies that the original source of the review is Google. ⭐️⭐️⭐️⭐️⭐️ Athlon Fitness is hands down one of the best gyms I’ve ever trained at! The trainers are incredibly knowledgeable and genuinely invested in helping you reach your goals. The atmosphere is always welcoming, motivating, and full of great people who make you feel part of the community from day one. I particularly love how they make use of the outdoor space, it adds such a fresh and fun dynamic to training. There’s always a trainer on hand, ready to give advice, encouragement, or just a little push when you need it. Whether you’re new to fitness or more experienced, this place has everything you need to train effectively and enjoy the process. Highly recommend! 💪Posted on Kerry YatesTrustindex verifies that the original source of the review is Google. Incredible trainers for all abilities. Especially like the group training sessions. Well equipped gym with nice balance between strength and cardio. Dave and the team are fantastic, extremely friendly, dedicated and passionate about all things fitness, health and well being. Highly recommend.Posted on John SeamanTrustindex verifies that the original source of the review is Google. Athlon Fitness in Ware is fantastic! Mike and Kerry are brilliant trainers — both for personal training (PT) and small group personal training (SGPT). They’re knowledgeable, motivating, and make every session enjoyable while still pushing you to get results. The gym is in a great location with plenty of parking, which makes it super convenient. Highly recommended!Posted on samad abdulTrustindex verifies that the original source of the review is Google. Great gym and community, solid pricing with class options.. and most importantly about 50 different barbells 😂Posted on Michael WhitingTrustindex verifies that the original source of the review is Google. Best gym in Ware! Very friendly and supportive staff and personal trainers. Dave the owner is a great guy and looks after everyone. There's a great sense of community here and everyone is very friendly and supportive, whether your're experience or new to fitness, Athlon Fitness will certainly look after you! 😁 They run really fun fitness classes and have access to an outside field so you can train inside or out. Plenty of parking in the carpark. I would highly recommend Athlon Fitness to anyone.Posted on Nikk LambTrustindex verifies that the original source of the review is Google. Great gym Great staff Good atmosphere KnowledgeablePosted on David RowlandTrustindex verifies that the original source of the review is Google. Went for a trial session on Friday evening. Pretty much empty and had the whole gym to myself. Has everything I need to do. Pull up bars, power racks, etc. I was looking around Hertford for a gym that had everything I needed and Athlon had it. The only reason I decided to go here was because Puregym in Cheshunt only had 1 bench press. Here you have at least 3-4 setups. I haven't been during busy times but its a 5 star gym for me anyway.Posted on Louis Nguyen
