Jan Ekstrand thinks every hamstring injury is preventable. “All of them?” I asked him during a Skype conversation last week. “Yeah, I think so,” he replied.
If you don’t have someone to hold your feet, you can do these with a lat pulldown machine, too. Just face the opposite way and put your feet where your thighs usually go. But know that your hamstrings will likely be really sore after the first time you try the exercise, reducing your ability to walk the day after.
