Ring Fallout Anti-Extension Progression
Anti-Extension trunk and pelvic control should serve as the foundation to any well-designed training program. Athletes who can command sagittal positioning of the spine and pelvis will have more success developing frontal and transverse plane strength and power down the road.
Following success with static sagittal plane progressions bear plank > modified plank and front plank I like to progress to using static-dynamic drills like fallouts and rollouts.
Traditionally, I have used stability balls and wheels for rollout drills but a suspension trainer like @perform_better gymnastic rings or a @trxtraining could be used for the fallout variation.
Start with the athlete in a tall kneeling position directly under the pendulum for the kneeling variation. To progress simply have the athlete stand up to lengthen the lever. To progress the standing variation have the client move their feet back increase the load and range of motion. The rings should be at waist height for both versions.
