On this photo: I am ready to do one of the best exercise to build the most effective, flexible, return blood and lymph pumping muscles, I am ready to push up the the 135 lb ( 61 kg) back pack.
We build as much flexible, most effective muscles, as the weighted belt or back pack we lift.
If the person can lift one's own body (no mater what body weight he or she has) the person produces no score and no "flexible" muscles, even if he or she does 10.000 repetitions. To win a score and build effective muscles, we have to lift a weighted belt (plus weight of one's own body or part of it).
