The holds on the board itself are very tendon friendly. All of the pockets have a slight slope to them so as not to overstretch the tendons when hanging open handed, and the crimp edges are slightly in-cut meaning you are less likely to explode off them and rupturing something in the process. The complete absence of any big jugs on the board aim it more at the intermediate to advanced climber, which is the only sector which could advisably use the board in any case.
I've been using the board for about two months now, and I have seen some gains. One thing I have found to be true of this board is that I feel far fewer aches and pains following a hard session due to the holds being a friendly shape without diminishing the effect of them for training.
