Alright guys...so during track season, I've been looking for ways to get faster, and my friend recommended trying weighted crunches. Are these better than the normal ones? I've noticed that I can do less and get the same, or maybe better definition
But...
-Is the added strain bad for your back?
-Does it work different muscles than doing normal crunches till failure, like strength vs. endurance muscles?
