There is no time limit from what I can see however exercise is meant to be carried out local to home , i really do question if he's staying local plus exercise is meant to start and finish from home which is another grey area as the other day he cycled to another area to go hiking , now yes he didnt drive but he did travel by bike and again not staying local , hes not massively breaking the rules but at the same time not really sticking to them either
Funny that the award is this week and he's posting more than he has done in months in his groups fb page and he's clicking like on others posts ,ive not seen him do that before, its almost as though he's jogging memories that he's there
