Hey, there hope this helps
Explanation: Both types of hurdle stretches loosen up the hamstring in the same way. But the hurdle stretch with the leg pointed back puts sideways torque on the back knee and can result in serious injury. So while the potential benefit of the exercises are the same, one risks serious injury to the knee.
Good luck :3
Use protection and be safe as much as possible.
