How's the first week been going?

Hi Lenny, I've done 3 sessions this week so far and I think it's been really good. It's also improved my sleep. Really happy I signed on 😊

L, you've been with us a while now. What's kept you coming back?
L.C.
I love being a part of this gym. Busy mum with 4 kids, but with the way that training is set up, and help from the coaches, means I've stuck at it for 18 months, and not looking at stopping any time soon. I'm much stronger now!
