You should never train the same muscle group each day. After a workout you should give your muscles 2-3 days rest.
ex; If you train your biceps on monday, then don't train them again until wensday/thursday.
Take in alot of protein and don't use to much weight. The best way to find out the right amount of weight is when you can just do 12-15 repetitions of the movement. You should focus more on doing the right movement then stacking up the weight
