The quickest way to build muscle is to start lifting weights. Start off with lighter weights until you can lift them easier and start increasing the weights.
Start lifting with what you are comfortable with and then gradually start adding weight. Ex. start lifting 5lb, next week (or every other week) make it a 10lb weight
No. Lifting weights is an excellent exercise and unless done to excess will not be harmful.
