Hi gang. I am working with a personal trainer who has designed a lifting program for me but it’s designed for free weights. My plan has me aiming for 12-15 reps per exercise x 3 sets. When I hit 15 reps I would like tonal to increase the weight. The second two sets are to failure. How should I design the custom program? Should I set it for 12 reps or 15? Should I use burn out or spotter? Trying to approximate a gym workout best I can. Thanks to everyone in advance!
