The hamstrings are the second most lied-to muscle group in yoga, after the hip flexors. We tell them to relax and lengthen, and then we lock the knees, hinge from the lower back, and wonder why the lower back hurts more than the hamstrings ever did. A real hamstring sequence keeps a soft bend in the knee until very late, asks the muscle to lengthen actively under load, and never sacrifices the spine to chase a fingertip-to-toe metric.
There's also the question of why the hamstrings feel tight in the first place. For most students it's not actual shortness — it's a neural protective response. The hamstrings are gripping because the glutes aren't firing, or because the lumbar spine is unstable and the hamstrings are doing the work of the deep core. Stretch the muscle in that state and it tightens harder the next day. So this class builds eccentric load before it builds range.
I keep bent knees as the default in every forward shape until pose nine. The shape may look less Instagram-friendly, but it's how the hamstring belly actually lengthens instead of the muscle yanking on its insertion at the sit bones. Proximal hamstring tendinopathy — that nagging pain right at the ischial tuberosity — is the most common over-stretching injury I see, and it comes from straight-leg forward folds cued to a stiff body.
Who this sequence is for
Runners, cyclists, desk workers, students with proximal hamstring sensitivity who are out of the acute phase, and anyone whose forward folds have plateaued for years. Also good as a recovery class after a hard lower-body strength day.
Modify heavily for: pregnancy past the first trimester (skip deep forward folds and seated wide-leg folds), students with acute proximal hamstring tendinopathy (no straight-leg work at all, even gentle), and hypermobile students with anterior pelvic tilt — they need posterior chain strength, not more hamstring length.
How to teach (or practice) it
Teach this as a stand-alone 40-minute class or insert the supine portion (poses 1 through 4) at the end of any vinyasa class as a cool-down. The supine work is where most of the actual lengthening happens — gravity is on your side, the spine is supported, and you can isolate one hamstring at a time without the other compensating.
Every student needs a strap and two blocks. The strap turns supta padangusthasana from a hopeful goal into an honest one — I tell students that if they can touch their foot without the strap, they don't need this class, they need a balance class. Blocks come under the hands in standing forward folds so the spine stays long.
Pacing-wise, I hold the supine and seated shapes for two minutes per side. Hamstrings respond to time, not intensity. Shorter, harder holds just trigger the stretch reflex and the muscle clamps down. Two minutes at 70% of end-range is more useful than thirty seconds at 95%.
When students ask why we're not doing standing wide-leg forward fold (prasarita) early, the answer is that it loads the proximal hamstring tendon at end range without warmup. I save it for the back end of class, after the muscle has lengthened from easier shapes.
