Zanthe S.
I made a bold decision to compete at the age of 50 in ICN Season B. This was a big step for me but my coach Montana and the OTF Team were right there with me from the start cheering me on. Montana was incredible. She kept me on track, provided the structure I needed and invested countless hours perfecting me posing. Her expertise in posing is remarkable and she had me nailing those turns in no time. And the best part on competition day I came 1st 🥇 in my division. This victory would not have been possible without the support and guidance from OTF. I can’t recommend them enough. If your looking for an incredible fitness journey and a coach who genuinely cares about your success go with OTF. I’m living proof that with the right support, dedication and an amazing coach you can achieve your fitness goals.

The training experience with Jonathan was absolutely amazing, enjoyed every second of it. He is very informative, helpful and energetic which makes training super easy! I hit a few of my milestones working with jonathan, some of which i never imagined i would have completed before starting with Off Tap fitness. I achieved a large range of things working with Off Tap Fitness and jonathan, such as, I gained a lot of knowledge about my diet, how much / how little i should be eating on a daily basis, I learnt all about daily macros and KJ’s and protein / Carbs / Fats intakes, and the effective exercises to work with these daily macros. I would hands down recommend this to absolutely everyone, from beginner to experienced, there is always something more you can learn and this process has been absolutely fantastic, I really wish i could continue working with OFF Tap Fitness.

She has been my coach for a couple of years now and I could not recommend her more! With her coaching I have met goals within a sport I never imagined reaching and I continue to make great progress. She's personable and tailors to MY specific goals and needs. Not to mention the infectious energy and great passion that she brings to her coaching. 10/10!!!
Stacey Foster
We've been training together for just over three months. In that time, I have learned SO much about training, lifting, and technique and my strength gains have been incredible. Your knowledge and passion for strength training and powerlifting are inspiring and your energy is infectious. You genuinely care about how your athletes are doing, knowing when to push and when to back off is a real art. I look forward to our weekly sessions and I'm excited for my future in this sport.
Grace Beddis
She has been my coach for almost 3 years now and I've loved every moment. I've progressed in my powerlifting while remaining injury-free and have gone through different seasons of life with my training adapting to suit. The gym is amazing. It's awesome to be involved in the best space with the best team—so much support and hype!!”
