Another Workout Answer from Quora

I’ve been lifting weights for a few weeks now and I don’t really feel any stronger, for example, one day I did 70 reps and another I only did 40. What’s wrong with me?

First of all, don't be doing such high volume. Increase your weights until you go to muscle failure after 8–12 reps only for upper body, and 12–20 reps for lower body. Muscle failure means you absolutely cannot do one more rep.

Work up to three sets of these per workout. Even if you have to add 1/4 of a pound, increase either the weight or the number of reps each time. This is the definition of “Progressive Resistance.”

Secondly, make sure you take a day off to recover. And add supplements such as whey protein, NOS, and creatinine. You will make rapid progress at first, and while you think you may have plateaued, each small increase adds muscle mass and density.
