Planks are a great exercise that strenghtens the “core” muscles. The side plank is a little variation of the regular plank, and it hits more of the…you guessed it…side of the body!
What you do
Lay on your side
Press your body up, using your elbow and feet
Hold your body up for 10 sec. or longer if you can
Here is a great little video, that even has a few advanced modifications if you want to take it to the next level!
