Bend your elbows and perform a push-up, keeping your abdomen contracted. Perform 3-4 sets of 15 reps each.
Cobra

This exercise is the easiest. Just place your hands at chest height and place your palms on the floor.
Then, lift your body by stretching your arms, while keeping your back straight and your abdominal muscles contracted.
Support your body with your toes and hold for 2 to 3 minutes. Repeat 5-10 times.
Plank
The classic plank, i.e. the front plank, is one of the best for acting on all abdominal muscles. This static exercise also allows you to train the buttocks, legs and arms.
Lie on your stomach and lift your body by resting on your forearms and toes. Stretch your body and try to keep it straight. Stay in this position for a minute, then rest and repeat.
Now that you know how to do these exercises correctly, add them to your routine to tone your arms and abdomen at the same time.
