The Pilates Plank is called Leg Pull Front, and can involved lifting one leg and working the calf.
I always say that Pilates contains all of the basic body weight exercises within the system - including squats, planks, side planks, bridges, and push ups. And there are also plenty of squats and lunges to make everyone happy.
In my last video post of the Daily Core Exercises, many people commented that they were starting to do planks for full body and core strengthening.
I have a video for that! The Pilates plank shows up twice in the mat - leg pull front and the push-up.
Presenting my video on Planking - how to properly execute, modify, and add variation to make the basic exercise harder.
If you are adding the plank to your workout, this shows you how to do it correctly.
