Straight Leg Lunge

Try this "fun" exercise:

Straight Leg Lunge: using a chair or bench, place your back foot on top of it and step your front foot forward. Making sure your back leg stays straight and your front knee stays behind your front toe, bend down and up 25 times on each leg. You can add weight or not. I do these without weight and still feel it the next day deep in my inner thigh and hamstrings.

Add this exercise to your leg routine doing two to three sets. Enjoy!
