Do hamstring stretches actually make your hamstrings longer?
Padraig asked about the best way to stretch his hamstrings. It depends on what you want from the exercise.
If you just want to loosen out in the evening, a standard stretch where you’re standing or lying on your back is fine.
If you’re trying to improve hamstring length, eccentric strength work is a better use of your time. Eccentric means the muscle is working while it lengthens. A few options:
• Romanian deadlift or another loaded hip hinge
• Eccentric hamstring slider, with your heel is on a slider disc (or a woolly hat on a wooden floor) sliding away from you
Research confirms this kind of training can increase fascicle length, so the muscle gets longer and stronger at the same time. Stretching on its own won’t strengthen the muscle.
Have a question about strength training for running? Leave it in the comments and I might answer it in the next video.
