People say to build muscle you need to lift heavy, and that when you feel that burning sensation in your muscles it is working. But when i am lifting heavy, eg. 5 reps, 5 sets, i don't get as much of a burn as i would if i was doing more reps on lighter weights. Does anyone else find this happens?

    The burn results from a build up of lactic acid which usually happens with more prolonged exertion or fast, anaerobic exercises like sprints. It's just an accumulation of metabolic waste and doesn't necessarily correlate with the effort you are exerting. Muscles grow (hypertrophy) due to progressive overload on the muscle fibers which. Doing light sets until your muscles burn may feel more effective but you are just getting a "pump" from blood and metabolizes enogrging the muscle.

    He's saying don't worry about feeling a burn. The weight should feel heavy and difficult to move - if not, increase the weight.
