ok so the last 25 days or so i was on winter break, was only lifting twice a week (i do powerlifting). And i took no pre workout supplements just generally went in and warmed up and had an ipod, i noticed ZERO strength losses or zero motivation issues. I think it saves me from overtraining too. Along with this im knocking out the fastfood which isnt often but usually a healthy option from TB or McDonalds or Subway etc.. This is saving me about 70-100 a month. but most of all i dont think ill feel any difference at all any negatives about not taking a preworkout strength wise?
