A couple of friends and i were reading this post, and they made some suggestions, due to the fact that they train with bodyweight sets only, and look amazingly big.
My friend francois said that he does a 10 x 10 protocol 3 times a week, and he said it was because of his tempo:
" I lift myself up in the speed at which i feel the hardest muscle contraction for the longest time, and go back down in a speed in which i feel the muscle as tense as possible, almost as going up, this is at the maximum tension possible( he usually gets 1 second on the way up and 1-2 seconds on the way down) so i get a pump from rep #1 to my last rep"
He explained that he began with 10 sets, and at first, they were sets of 10, but in time, he reached sets of 15, so he added weight.
My other friend, Pietro, he sais " I just aimed to get as many reps in good form as possible..a hard and explosive concentric which didn't help me with its momentum, and a controlled eccentric. I aim for maximum reps, so i don't put too much into the eccentric, i exert control, but I try to use as little srength as possible in order to save my energy for the lifting, since I am trying to get as many reps as possible( he gets a full rep done perfectly in 1 full second, or 1,2 to 1,5 seconds, always keeping an eccentric phase longer than the concetric, like a 60/40 ratio)..However, I always make sure to keep a decent level of tension in the muscles targeted. I may start with a first set of 20, and end up in a last set of 4. Do this twice a wek and you will grow"
My own advice is to alternate their programs..I train 2 times a week,a nd in one day, I use the routine Francoise uses, and on the other I use Pietro's routine. So far I seem to be catching up with their physiques
Hope this helps
