It is the classic plank. How to do it? You have to face down, as if you were going to do a push-up, but resting your elbows and toes on the ground. You need to hold this position for at least 30 seconds and keep in tension the abdomen and buttocks. The back must be straight, and not arched.

If you’re a beginner, try increasing the plank for another 10 seconds as the weeks go by.

Plank 2

In the same position as in the previous exercise, but instead of keeping your legs parallel to each other, you need to cross them. Yes, while your elbows are still on the ground, bend your right knee towards your chest; do the same movement with the opposite knee. If it feels too hard or to start you can straighten your arms
