GET A GRIP
if you hit failure in set due to forearm fatigue while you still had a few more reps left in your back (target muscle), then you're not training your back to its potential either. ?? Your back muscles are much larger than your forearm muscles and you don't want to limit your back strength to your grip strength. At the beginning of a workout, while you're nice and fresh, use your grip. On your heaviest sets, and towards the end of the workout when your grip has fatigued..use straps so that you can focus on the targeted muscle group and not have to worry about your grip failing.
