Modified Single Leg Step-Ups
This next exercise may look familiar, but it has subtle variations that make it much harder and more effective.
Now most people have probably done some sort of leg exercise where they stepped up onto a box or bench. In the very least most of us have walked up a flight of steps! In this exercise we are going to try and take away any and all assistance that the lower leg provides. This will essentially force the body into a one legged squat.
First thing to notice is that my bodyweight is shifted forward over the top leg. This is to help ensure that I press only with that leg. The second and most important feature of this exercise to take note of is my bottom foot.
I am dorsiflexing the foot, which is just a fancy way of saying that I'm lifting up and holding my toes at the start of the exercise. In a regular step-up, you would instinctually press the ball of this foot into the ground as you flex your calf and ankle to help lift your body up. By lifting up the toe and keeping them off the ground, the calf can no longer help lift you up.
You still need to be careful not to flex and extend your knee when stepping up. This will assist your other leg and reduce the effectiveness of the exercise. So keep your toes up and concentrate on not moving that bottom leg at all. There should be absolutely no movement in the bottom leg. None. Zero. Nada.
This exercise is difficult for two reason, first is that when done correctly the top pressing leg is essentially doing a one legged squat from the bottom up.
The second difficulty is overcoming your natural reaction to use that bottom leg. Again, don't flex at the ankle or knee! Only press with the top leg! If this exercise is easy the first time you do it, and you can't do a pistol yet, then you may very well be doing it wrong!
Obviously you can increase or decrease the height of the step to make the exercise easier or harder. If you don't have an open box like I have in the picture, then stand so that your free leg is to one side or another of the box.
Weighting the exercise down is also an option and in my opinion, more comfortable than trying to weight down a pistol. More on that point at the end.
