Kneeling with the resistance band across the upper body — the setup for opening and activating the rib cage. Title cue: 'Train your RIB CAGE + ABS'.
Plank variation with a 10 lb medicine ball under the lower back (deepest abs) or against the chest (serratus focus). Elevate the feet on a foam roller for the harder version.
Lying on the side with the medicine ball, driving a cross-body connection — obliques and rib-cage rotation through the midline.
Seated with the resistance band, arms extended at shoulder height. Alternate wide and narrow arm positions to work the intercostals and infrasternal angle.
