Hello,
two friends of mine said that it is wrong to extend the arms fully when you start a pull up from a dead hang (so it follows that you shouldn't fully lower yourself before you start the next repetition).
Their argument is that extended arms supposedly put too much stress on elbow joints, which will supposedly cause injury problems. They say the same thing about dips; That you shouldn't fully press yourself up.
My question: Do you agree with this statement?
I have only been paying attention to the shoulders. But not extending arms seems like "cheating" to me because in my opinion the first few percent of the motion are the hardest (or at least it took me the longest to learn them). I have also never heard of this suggestion before even after having read many websites on the topic. My friends have apparently received some advice on this by fitness coaches and maybe physiotherapists (not sure), so there may be more to it.
Thanks!
