Seated bent over lateral raise. An isolation pull exercise. Muscles worked: Posterior Deltoid, Lateral Deltoid, Infraspinatus, Teres Minor, Rhomboids, and Middle and Lower Trapezii. Also known as seated rear delt raise.
Hanging leg and hip raise. One of the most effect core exercises. See website for details. Muscles worked: Rectus Abdominis, Iliopsoas, Tensor Fasciae Latae, Sartorius, Pectineus, Adductor Longus, Adductor Brevis, and Internal and External Obliques. Without contraction of abdomen, abs only act as synergists, and the exercise becomes just a hanging leg raise.
