My poor house would not be able to withstand me throwing medicine balls around. Syaigh, I see you often just log "abs" in your workouts; what specifically do you do in terms of exercise, sets, reps?
How 'bout ab wheels? Any utility?
Well, good question.
I have a very long torso and I had a rectus abdominus repair (I had a massive diastasis recti from three pregnancies and a pre-existing umbilical hernia) so ab wheel just doesn't feel that good to me unless I keep it under my shoulders, ie not go all the way out. I know a lot of people who like them and do them, but I think they tend to be hard on the shoulders unless you have big lats.
I used to teach a kettlebell fitness class three days a week and mostly did swings, twists, squats, lunges, TGU's and windmills, and woodchops for core. The ladies would occasionally challenge me to have them do traditional abs because they didn't think they were working core. I never did situps so I told them that if any of them could do more situps than me, then we could start including them. They never could. Now, I was also doing a lot of barbell work at the time both powerlifts and Olympic lifts so I think that added a lot of stability.
BUT, there was a time I doing some krav with a self defense instructor and found that kicks, especially knees, killed my lower abs so I felt that leg raises or hanging knee raises were definitely important.
Nowadays, I surrendered my training to a figure coach so she has me doing bicycle crunches, V-ups, med ball overhead situps, V-sit Russian twists, crunches, and lying leg raises. I'll be honest, its not been particularly difficult, but I engage my core a lot to stabilize other lifts (and riding horses) so I think my core is relatively strong.
But, my overall feelings about core work still are this:
1. Rotational work, either standing, lying, or seated is highly underrated (I love full contact twists in addition to what I listed above).
2. Leg/knee raises hit the abs in a way we just don't unless we are regularly sprinting, kicking, or jumping.
3. Ab flexion may have its place but I don't think its as valuable as the above two. Definitely worth visiting from time to time, but if the obliques and back extensors aren't strong, this can be really hard on your back.
Never eat more than you can lift.
