This video showcases the ab workout of the famous boxer triple g, I was surprised when he was doing sit-ups and side crunches with his legs held/strapped, isn’t that considered assisted ? I used to keep my feet held under a couch when doing sit-ups but a friend told me that if I want to target my abs better I should do them without my legs held. What do you think I should do legs held or not( also I am not doing it for the aesthetic like bodybuilding, I am also a boxer)
