my favourite chest exersize....... when i could train propperly they were my number one for chest..... i used to lower it a midgies dick just above my collar bone, i wish id never flat benched and went straight to these...
for me personaly id tend to work up to one heavy set, if i was feeling good id add an extra set and go even heavier maybe 4 or 5 reps and do a drop or a double drop from that. Everyone is different tho, altho my brother has the exact structure as me, and he's been able to go straight to the sweet stuff off the back of my years of trial and error
