World's sexiest math teacher reveals workout secrets

With over 1 million Instagram followers thanks to a photo taken by students during class, the math teacher and hottest male model in the world shares exercises to look sexy and attractive.

Pietro Boselli (28 years old) is a teacher from Negrar, Italy. During his time as a teacher of advanced mathematics at the University of London, he also worked as a model for major fashion magazines. Currently, the Italian guy is pursuing a modeling career.

Legs and hips:

Keep your back straight and squat. Lift one leg up and keep your back straight, then squat down while keeping the other leg straight. Raise your arms straight out in front of you for balance. This will tone your legs and hips.

Note, if you do not keep your back straight or do not maintain balance, it can put too much pressure on your knees and lead to injury.

Abdominal muscles:

To properly train his abs, Pietro Boselli uses a ball to stretch his body while exercising. He starts by sitting on the ball, then lying straight with his arms out in front of him, holding it firmly to balance his body. Keeping his legs straight, he moves them up and down perpendicular to his body, sliding his hips to move the ball rhythmically.

Things to avoid: Slide your body off the ball. Also keep your legs straight to maximize range.

Shoulder:

For this exercise, take two dumbbells of whatever weight is comfortable for you. Raise the dumbbells straight out in front of you and out to shoulder level. You must always control the movement so that the dumbbells do not fall.

Things to avoid: Lean back or arch your back. To do this, you need to keep your back straight and both feet firmly on the ground.

Chest:

I always like to have fun through clapping, it's very good for exercising the chest and upper body muscles," said Pietro Boselli. Do a push-up-like movement, when pushing yourself up high, clap your hands under your chest before touching the ground.

Be sure to keep your body straight while pushing yourself up.
