This may be true to an extent. I go to the gym and it motivates me and helps me a lot so it's not completely useless the way this video makes it sound.

As Zahra mentioned I also have a gym membership and that within itself motivates me. Some people are different than others and to be honest when I start slacking but continue to see money taken out my account for my membership it makes me realize this is something I invested money in for my health. Use it. Before a membership it was here and there but once I signed a one year I've seen more progress and determination within myself than ever before.

No, I prefer to exercise in other ways than the gym which could be boring and wasteful if the membership isn't useful.

I needed this! Made my night! :)

I don't have much space at home for fitness equipment so I prefer going to the gym. I also feel motivated by going.

I find it a social motivator, I have friends going to the gym this motivates me to go too
