So my stepdad wanted to start to workout. He is a GolfPro,chainsmoker and hasnt exercised in 30 years. Has been in several car crashes and has an array of back and shoulder problems. After some hill sprints (3*7s) he was at the point of nearly fainting. We did some F1 after and due to his big stomach he couldnt do the PE1 of the SLS, he however did the PE2 instead and all the other exercises of today went well (MnPe1/SLPe1 and some weights) as well as their IM. The reason Im posting is: is it okay to skip exercises he cant do due to his injuries/body state? And are there any thing to keep in mind especially due to him being overweight and having injuries in his shoulder and back?
Thanks
