If your trainer gives you x sets left arm/ lev and x sets right arm/ leg we need to be able to enter the reps for left and right, one side may be less and it’s good to note which arm it was without typing messages in the chat. I want to my trainer know for example if I did single arm bent over rows 9 reps left and 8 reps right then I didn’t meet my rep target of 18 and he needs to know where I feel short.
