Is pushing too hard at lifting weights good?

Answer 1

Working so hard that you cause yourself injury is always bad. That being said, pushing as hard as you can without injuring yourself will be the most effective way to build muscle. If you are unsure about how much weight you can lift or how many reps you can do, it's a good strategy to start at a weight you know you can do at least 10 times comfortably, and work your way up. If you feel that it is too easy, you can simply step up to the next level. Going too heavy too soon is the best way to injureyourself.
