Somebody the other day told me that pullups are a great exercise to do, and so I decided to try and do some. But I only managed 6 before I was really struggling. It kinda disheartened me, so I am wondering should I carry on do pullups, and try to do a couple more each week, or should I just get stronger with weights first before I try them again?
Also, are pressups any good for your chest and shoulders? I have just brought some push-up grips, and I try to do 5 sets of 20 press-ups a day, mainly becuase I don't have a weight bench therefore I can't really do anything for my chest. I just wanna know am I wasting my time, or will they help me build my shoulders and chest up?
