How do you value these? They are fun and challenging if you have some really heavy DBs. Everyone lists them as a core exercise, but the only limiting factor is keeping my arm locked out during the movement. It looks like there's a lot of oblique work, but I don't feel anything other than my shoulder stabilizing. Do you do these often? What kind of rep schemes? I think I might just do these once or twice a week since I can do them at home. My workouts are usually me picking a squat + push + pull + core + grip, but you can see I often need to cut some gym time; I can just do these like homework. I did them for the first time this week. WT x L/R 45x5/5 (1/4 bw) 60x5/5 (1/3 bw) 90x3/3 (1/2 bw) Next time I'll try to do a pyramid at similar intervals ([email protected], [email protected], [email protected], [email protected]?, [email protected]?, [email protected]). Where is Xtrainer when you need him?
