One of my goals for this year is to master the full Planche but in order to do that I need to increase wrist + forearm strength and add some size too.
Doing plenty of bodyweight resistance stuff to help this but bought these hand grips to use at any moment throughout the day. Up to 50KG of resistance per hand doing 3 sets of 12 each time for hypertrophy. So far though 50KG is a bit much so the dial is turned down to about 35KG. For the £11 they cost, there is lots of room for progressive overload before these become easy.
Can recommend!
