@tylerpath: This may warrant an entire explanation, but the best way to maximize the involvement of your entire abs isn’t to simply curl as tightly as possible like a fruit rollup. This is because on a bodyweight ab crunch the direction of resistance is bound by gravity (directly downward)… thus there is little to no resistance on the upper abs in the last 1/3 of the crunch where the direction of spinal flexion is horizontal (rather than vertical against gravity). So instead, if you aim upwards in the second half of the range of motion, sure we won’t shorten the abs as much technically, but we’ll be able to maintain more resistance on the entire rectus abdominis (notably the mid to lower abs) since we’re getting spinal flexion more directly against gravity (the resistance) #fyp #Fitness #gym #bodybuilding
