Up-down Plank
The up-down plank engages your biceps and is also considered a cardio workout if it is done quickly. It involves resting your body weight on your forearms.
How to perform an up-down plank
- First, take a lowered plank position and have your weight resting on your forearms
- Then straighten on arm, so your palm is flat on the floor
- Straighten the other arm, this way both arms are flat on the floor and you are in a normal push-up position.
- Reverse it again. Lower one arm, so your forearm is on the floor.
- Lower the other arm, so you have both forearms on the floor. Now you are back to lowered plank position.
- Basically, go back and forth. Repeat from the second step to the fifth. And count the number of reps.
