How To: Hanumanasana (longitudinal splits)
If you are working towards longitudinal splits you will need to prepare two areas of the body: the hamstrings of the front leg, and the quads and hip-flexors of the back leg.
Watch this video to see how to stretch these areas of the body in preparation for splits. Remember to warm up the muscles first by doing some dynamic or static strengthening (“warming up”), and when you start moving into splits aim to keep your hips square without letting the back-leg-hip open too much.
Most importantly have fun!
