Pietro Boselli's Workout

Pietro Boselli - Fitness Athlete

Pietro Boselli (born 3 December 1988) is an Italian model, engineer, and former mathematics lecturer at University College London.


Boselli was discovered at the age of six and began modelling for Armani Junior. He later went on to study mechanical engineering at University College London, graduating with a first class honours Bachelor of Engineering degree in 2010. He started his Doctor of Philosophy candidature in 2010. During his PhD candidature, Boselli taught undergraduate mathematics to mechanical engineering students. He completed his PhD study on 16 February 2016. In January 2014, a student took note of his physique and stumbled upon his modelling career; the subsequent Facebook post went viral a year later. After the viral post, Boselli signed with the British modelling agency Models 1. He has since been dubbed the "world’s sexiest maths teacher." As of April 2020, his Instagram account has 2.7 million followers.

About the Program

Category: Hypertrophy

Pietro performs a classic routine of the weider type that bodybuilders have been doing forever. It consists in working the muscles only once a week and only one muscle group in each workout session. The only variant we found is that he trains legs for two days.


The key to his routine is to accomplish a high distress of muscle mass, which is achieved with moderately high reps. Always between 6 and 15, with a large number of drop sets, failure sets and pumping until the muscle is completely exhausted.


Rest Time

Rest between sets should be between 45 and 90 seconds. The most common thing in a weider routine is not to re-train a muscle until the following week.
