Hip Abduction
Bone density priority — femoral neck T-score -1.2
MWF schedule (3x/week).
Network meta-analysis: 3x/week shows statistically superior femoral neck BMD vs 2x/week. Hip abductors generate highest lateral strain at femoral neck.
LIFTMOR trial (Watson et al., 2018, J Bone Miner Res) is the landmark RCT.
Captain’s Chair
Bent knee raises — progress to straight leg
Abs 3x/week (MWF). Research: 2–3x/week optimal; daily training counterproductive. Captain’s Chair + Crunch are complementary — upper vs lower/oblique emphasis. Straight leg is a load progression, not a different exercise.
