Trunk / Spine Isometrics. Seated
Standing, Split Stance, Half Kneeling (supported or unsupported), Half Kneeling Alignment. can go all 4 directions on the trunk. Or Single Arm (SA) – (Fwd or Bck)
Shown here SA Seated (primary focus spinal rotators isometrically.
The trunk rotation strength has numerous ESSENTIAL aspects. Shown here; w MLB for rotary patterns. Any other sport w heavy rotatory motions (softball, boxing/combat, tennis, golf, etc). General fitness / wellness for right / left symmetry for proper joint health and optimal muscle function
But take it a step further with regards to SPRINTING (or jogging or running). It’s obvious that on multidirectional motion, pelvic approximation leading into spinal rotation is important. But what about straight line linear sprinting.
