I tried this last night for chest and triceps. 1- Holy shit 2- 15 seconds goes by very very quickly when your muscles are burning and you’re trying to fill your lungs. 3- I gave myself some extra time on a few different exercises. Being it was my first time I erred on the side of caution so I didn’t injure anything. Getting older and wiser lol. 4- looking forward to doing it today with different muscle groups!
