Hey guys. This will sound like a stupid question or a string of very ambiguous/far-fetched hypotheses but bear with me.
I've been thinking about what exercise to implement into my workout regimen to support steady progressive overload for the abs. Meaning, of course, that I can very accurately measure progress, and increase the loading for the exercise.
My thoughts: Janda just might do the trick. It's almost an isolated movement, but it takes great finesse to master the technique and keep the "groove" of the movement. For me, almost daily practice is needed to keep the legs down = the technique fresh in my mind.
Standing wheel rollouts, are awesome. It is very difficult, however, to measure progress when you've made it to doing 1-5 reps with a full range of motion. To add weight would compromise form due to the movement: It's not strictly for the abs.
Hanging leg lifts is another great movement. Adding weight to the ankles works up until your grip gives out. So that's a no-go.
Dragonflags cease to be difficult after 10-20 reps, and it puts a lot of stress on the elbows and the shoulders, which are less powerful than the abdominal muscles (is it so? I dunno. I'm just throwing it out there.).
What about normal crunches done with a weight behind your head? It seems good and close enough to the only steadily measurable ab exercise. That, or a crunch done on a swiss ball with a smaller weight to increase the range of spinal flexion.
L-sit holds are great, they build crazy strength in the abdominals, but the range of motion is 0, so you've got a lot of strength on the static position, but it doesn't carry that much into the full range of motion.
Any thoughts on good abdominal exercises? This is largely due to the fact that I'm starting a mass-gaining phase in my training, and looking for movements I can easily measure progress in. Oh yeah: Holding the lockout position of a deadlift in a smith-machine is a great static core drill, but that also requires grip strength..
