hi, from you experience and what you know....do you think that combine these two training you can help yourself to develop a skill?!
for example weigthed pull up helped me a lot to increase my strength in front lever, the same thing i can say for the slow forward (lento avanti) helps me for the full rom hspu..
do you thing there is a exercise wich can help to develop planche?! like deadlift?! i suppose it because if i think about the passage between tuck to straddle planche is always a motion of hip extension or not?
