We seem to be turning into a big bag culture. Purse sizes are enormous. And have you seen the over stuffed backpacks on 6 year olds? So when it comes to carrying your work out clothes you are way overburdened. So you just won't carry another bag, so then you just can't work out. Well help is on the way. Lockers - just like gym class in middle school. Most gyms have permanent lockers that you can rent, for a small monthly fee. You can stash all your gear in the little locker as well as your post work out beauty supplies. So you don't have to lug all that stuff around.
Fit's take: The additional fee of the locker is minimal compared to the waste of a monthly gym fee for a gym you aren't using. So splurge and get a locker.
