I am doing weight-lifting 3 times a week, 2-3 hours for each workout.
Now I got a gift of arm weight adders (basically, a sand bag wrapped around forearm, each bag weights 1kg). I'm considering wearing them at home, during my everyday activities, to give my arms some extra training (seems the biceps will get the biggest impact).
Will that improve my training results or will it simply lead to overtraining?
