Anyone ever do these at the same time.. I do carries for up to 12 minutes (depending on weight of bag)... 6 minutes bear hug or zercher and 3 minutes each shoulder.... I one day realized my other arm was doing nothing so I put a kettebell in there..... Started with a 35lbs for the past month, now I started with the 55lbs and will probably bounce back and forth between the two..
Anyone else do these?
