"I motivate people throughout sessions- it's about knowing you can always push that bit harder."
Camaraderie is a massive part of Ben's world ("the gym's like a massive family"), so what's his advice if you're exercising with mates? Matching fitness levels isn't a must. "I like training with different people, as it pushes my limits." You heard the man- get that buddy workout booked in.
Train like Ben
"Don't be scared of weights- they're not going to make you bulky."
"Fuel yourself right. "I find a lot of women under-eat for their energy needs- it's amazing how many calories your body burns just by being alive."
