Should a low B.M.I keep you out of the gym? In some cases, it might.
In an effort to cater to bigger clientele (and beginners who have more weight to lose than just the last 15-20) some gyms have started ‘banning’ thinner individuals from joining. The hope is that it’ll encourage larger exercisers and newbies to stick with the program and create a more positive experience for them by minimizing self-esteem sucking comparison and creating programs for their specific goals.
Is it discrimination? Yes. Literally. But is it necessarily a bad thing? This is where I get a little more defensive.
