Did you know that flexing your muscles can grow them without even using weight? The best time to flex your muscles is after a working set so after you finish your set I want you to really flex those muscles and hold for as long as possible maybe 20 seconds,I want you to continuously do this threw out your workout on the muscle you just worked. This gets a massive stretch on your muscle fascia because the muscle is already filled with blood you are going to get a massive stretch with all the blood flow and this leads to massive growth. I have clients put on 1/2 inch in arms in 3 months using this technique, arms is the easiest to measure if its putting half inch on arms the rest of the body will be the same. You can be discrete you don't have to be up in the mirror in front of everyone's face pulling poses, you can do it sitting and people wont even know your doing it.
Flexing is like doing the ultimate set for your muscles you get full muscle contraction the best possible contraction there much better than using weights in fact and this is by far the best tool to promote new muscle growth.
