> People dramatically over estimate how much they burn working out. Not to mention many people spend just a fraction of their time in the gym actually lifting weights. Mostly sitting at machines, resting between sets and playing with their phone. My gym routine is "super-sets" pairs of exercises working complementary groups of muscles. So I'll do say 4 sets of lat pulldowns alternating with shoulder presses, with zero breaks. Then switch immediately to the next pair of exercises.... Net result is far higher average intensity in a shorter time.
