What Our customers say

I've been at Feelgood in Grantham for 12 years. I've trained at several gyms in my time and this is the best ever - no ego's here or pre-Madonna's! It's not just a gym - it's a community and a family. I received my Hall of Fame Myzone status in September 2018 and had a mini trophy engraved from Feelgood too! I like to train first thing at 6am (always the first person in the gym!) every Monday, Wednesday, Friday a small group of us or 'The Morning Crew' do 1,000 Battlerope Waves each and inbetween we go on the bikes - no standing about for us!

Barry Wilkins : 78 years

When I started at Feelgood I was 64yrs old - I had never been a member of a gym before and when my husband Clive took up Golf as a regular hobby, I wanted a new one too. When I started I was 15 stone and I'm now about 10! I take part in all the different style classes and I come to the gym usually four times a week - often doing back to back classes! I love the FG Burn because although there are several FG Burn classes on the timetable, they are always different! The whole team at FG are friendly and helpful and I love being a part of the community here. I also love the meals and snacks from the FG Juice Bar. My favourite is the Overnight Oats
