I started working with Jewelz and her team at Tighten Up in January 2021 and their expertise, professionalism, patience and positivity have helped me through Melbourne's endless lockdown. I was a complete novice but Kavisha and Phuong have been amazingly supportive and welcoming. Tighten Up has such a wonderful feeling of family and I have really missed this connection throughout lockdown. As for the results: I'm over the moon with my progress and feel fitter, leaner and stronger than I have for 25 years. They know their stuff and how to look after oldies like me! Thanks Guys!

I hate exercise. But I love going to Tighten Up! The staff are ultra friendly, attentive and professional and I feel taken care of. And I like the small group classes as a compromise between one on one training and large classes. These people make going to an exercise class fun for me, and believe me, that is a major achievement and is definitely worth five stars.

I started with Tighten Up in Oct 2020. Initially started so I could lose some kilos to fit into a bridesmaid dress (which I wore and felt fabulous in 3 months after starting!). Jewelz and Kavisha are so knowledgeable!! They give me so much variety in my workouts and help me stay on track to achieve achieve my fitness goals (100kg deadlift, chin ups, weight loss). Theyve also been a big source of support during Covid. Keeping the workouts going and always up for a chat. Since joining Tighten Up I definitely feel more me again!! So much stronger both mentally and physically.

I was trepidatious about returning to exercise after a three year hiatus. However, after spending one hour at Tighten Up, I knew it was going to be the place for me Jewelz and her team made the transition back to exercise seamless, and most importantly fun! The workouts are always diverse and the community is really supportive/encouraging. Jewelz really goes above and beyond for her clients; continuously checking in and ensuring youre staying on track to achieve your goals. If you want to feel like a valued member of the community, then Tighten Up is the place for you. Thank you, Jewelz

This place is fantastic. Professional staff who know how to push you just hard enough. Varied workouts to keep things interesting. And a friendly and relaxed vibe. I'd spent five years without a regular gym as I couldn't find one that I liked enough. Jewelz and her team have helped me get back into regular exercise and restored my previous level of fitness.
Highly, highly recommended.

Tighten Up fitness is like no other gym I have been to before, as its not. This studio is a community with professionals running the show. I have been attending here for over 4 years frequently and am still pushed and challenged in my workouts. The physical strength I have gained is something I never thought would ever be possible. The team here are experienced, engaging and very friendly. Its like be part of the family. The studio is beautifully fitted out with all the modern equipment with regular scans and checks to keep you on your targets. I have moved house since I first joined
