Stand with feet together, arms at sides.
Step in place begin to pull the raised leg high enough that the knee makes a 90-degree angle and is level with the hip (or higher).
Lower leg to the ground then pull the other leg into the same 90-degree angle.
Continue alternating raised legs in a high-kneed march.
This beginner's rendition of this simple cardio move engages and tones core, thigh, and hip muscles. The more controlled the motion, the better the ab and thigh workout. This easier version involves less cardio and calorie burning benefits than the more advanced versions, but still serves as a simple, effective tool for total body toning.
