Another method to release a lot of testosterone is to do legs more often.
You should not be doing full body routines multiple days in a row. You should be giving the body at least 3 or 4 days to recover from an intense full-body session. However long it takes to feel fresh again, let it recover. Legs are merely your largest muscle group, so of course they'll have the most impact. Of course, keep the work out to about 50 minutes or less, because cortisol starts to produce in your body and it destroys your testosterone levels (even for days after the fact).
