If Max wasnt so modest, I would put a pic of his back up. Nick saw his back on Saturday and was most impressed.
He cleans, shrugs, deadlifts, snatches, rows heavy weights, very heavy weights.
When it comes to chins, he does them dead stop, dead hang, at the end of his sessions. He pauses for up to 2 seconds between reps.
He can do over 20 in that fashion.
Its just the one exercise where I notice lifters are using the wrong muscles to initiate the pull, mainly due to the added weight.
Just an observation.
Oh, and before you guys say I dont add weight because I'm weak at them lol, I have done 20 @ 90 kg in the fashion described above, and 5 reps with 40kg strapped to me to shut up a fattie who had a long list of excuses why he couldnt chin.
They definitely feel much better without weight.
If you want to test back strength, powerclean something.
