This is a common problem for guys. Instead of beginning with light weights and actually finding contact with their muscles they takt a look at their friend and decides to lift heaver than him just to outshine him.
As a result they end up with terrible form, not knowing if they’re working the right muscles and sometimes it might even result in injuries.
So, make sure you begin with light weights and if you’re dragging a friend with you, make sure you both use light weights the first times. It doesn’t matter what you say – if you lift heavy, he’ll also want to lift heavy.
Most women have the oposite problem by being afraid of lifting heavy. Some underestimate themselves and others believe they will turn into a bodybuilder within a week. Both men and women need to learn this!
Lift light in the beginning so you learn the proper techniques and find contact with your muscles. Then you should increase the weight!
