What are some good training routines to gain mass? Its very hard for me to put on weight, and Ive wasted alot of time doing too many excercises only to find I stayed the same size.
If you're not putting on weight, the problem lies not with your training but your diet. Basically, you need to start tracking calories. Start eating what feels like a lot, and tracking it. If you find after 2 weeks you haven't put on weight, add another 500 calories per day and repeat for 2 weeks. Then you'll know how much you need to eat to bulk.
