Plank (Opposite Arm/ Leg Raise)
Starting in a low plank on your flexed toes and forearms (elbows directly below shoulders and abs and quads engaged) lift your right foot off the ground with your foot flexed. Lift your left arm off the ground and out in front of you. Lower them back to the ground simultaneously. Then do the same thing with your left leg and right arm.
You can also do these in a high plank. You will begin these with your shoulders, elbows and wrists all in one straight line.
Plank (Opposite Arm/ Leg Raise) are great for increasing total body strength, stability and coordination.
