4. Well hello there, what on earth are you trying to do? Sometimes people just become bored with the ordinary exercises. Lifting weight, doing squats, bla, bla, bla. We bet Tarzan didnt get those muscles by lifting weights on trees. Oh no, Tarzan must have experimented with all kinds of rocks and trees. And that is exactly what this guy is trying to do. Yep, he is now lifting his weight with his back and not with his arms. This is revolution, people.
