That's me with dips. I used to be able to strap on retarded amounts of weight with a belt and go to town. Now that I am bigger I can't do nearly as much weight on the belt. I do dips for chest also, very rarely as a tricep exercise.
The form is as you described it, upper arms must be parallel to the ground at the bottom of the movement, feet no more than 15" apart, body in a straight line.
my 15 yo step son does not lift. the only thing he does is karate. he is tall and skinny. i watched him do 184 full pushups no rest at the bottom nose to floor straight back the whole time.
just wondering, if you're training with weights and your pushup max is like 30-40.. is there any point trying to bring it up to like 80-100, will that help with size/ strength??
125. its no different then anything else.. you have to push yourself and work at it.
i end my chest day with 60 pushups
a trick to getting better at pushups is putting a 25 or 45 pound weight on your back. then once u train for a while take the weight off and it will be so much easier without the extra weight.
