Assessing the effect of sit up technique, Andersson et al. (1997) measured rectus abdominis muscle activity when performing the curl up (trunk flexion only), sit up (hip flexion only), and spontaneous sit up (both trunk and hip flexion) with either straight or bent legs, and either anchored or unanchored.

«The external and internal obliques facilitate lateral trunk flexion, i.e. side bending, and rotation of the torso.

Comparing hamstring strain injury prevention and rehabilitation exercises, Orishimo & McHugh (2015) found that the supine sliding leg curl (Slider) produced greater gluteus maximus EMG amplitude during the eccentric phase than the standing elastic - band resisted hip extension, the standing trunk flexion (Glider) or the standing split (Diver).
