Hanging Leg Raise & Plank
ANTI-EXTENSION & DYNAMIC FLEXION · BOTH PATHS
ANTI-EXTENSION & DYNAMIC FLEXION · BOTH PATHS
Why it matters · Operator The plank trains the trunk to hold a rigid neutral position under load, the most transferable core position in tactical work; the hanging leg raise trains the trunk to control the spine through motion while the grip and shoulders hold a dead hang. Together they build a trunk that both braces and moves under control.
Why it matters · Longevity Plank endurance correlates with low-back pain prevention more strongly than any single mobility metric, and the hanging work preserves grip and shoulder health, both of which track independence and mortality in the literature. A captain's chair station can stand in for the hang where needed.
Form cues
- Plank: forearms under shoulders, body one straight line, glutes and quads squeezed, ribs down
- Breathe normally; stop the hold when the line breaks, not when it merely gets uncomfortable
- Hanging leg raise: dead hang, shoulders active, raise the legs with control, lower without swinging
- Use a captain's chair if a full hang is too much for the grip
- Move slowly on the raise; control kills the swing
Common errors
- Plank: hips sagging or piking up to make it easier (the straight line is the standard)
- Hanging raise: kipping and swinging for momentum instead of controlling the rep
- Holding the breath in the plank, which defeats the trunk-training adaptation
Path A scaling Build the plank toward 60 seconds, dropping to the knees if the line breaks early. Start the hanging work with bent-knee or captain's-chair knee raises. Control before range.
Path B scaling Add load to the plank with a vest or a plate on the back once 60 seconds is easy, and progress the hanging leg raise toward straight legs. Keep every rep controlled.
