From there, you move to the plank position on your elbows, then back to the starting position.
Do as many reps as you can in 60 seconds, then move on to the next exercise.

2. V crunches

First, you need to lie down on the floor. Then, stretch your arms over your head. This is the starting position.
Next, stand up, bringing your arms straight and taut toward your legs, which you also raise straight.
The idea is to support yourself on your buttocks while trying to touch (or get as close as possible to) your feet with your hands. Then inhale as you return to the starting position.
Do as many reps as you can in 60 seconds, then move on to the next exercise.
