Hamstring stretches are particularly crucial if you're doing sprints. While sprinting is a simple form of high intensity exercise that does not require any kind of equipment and can be done just about anywhere, any time, it's also one of the most dangerous. Unless you're in phenomenal shape and have special training in sprinting, it's really important that you start gradually, and make sure to perform the recommended stretches.
I did not follow this advice and when I first started HIIT eight years ago. As a result I tore one of my hamstring muscles, which caused me pain for about four years. The stretching exercises I demonstrate in the video below eventually helped me recover, but I suggest you avoid making the same mistake and just do the stretches before you start sprinting. The stretches I recommend are so-called Active Isolated Stretches (AIS), not static stretches, and include the following:
- Hamstring I stretch (straight: 10 reps)
Hamstring II stretch (foot twisted slightly left: 10 reps)
Hamstring III stretch (foot twisted slightly right: 10 reps)
