Derek Lunsford did 100x 142kg on the back squat!

Last year's 212 Olympia champion, Derek Lunsford, is busily preparing to defend last year's title, although he will have his work cut out for him to beat Shaun Clarida, who is determined to take back his 2020 title. However, the 28-year-old Derek will be looking to take two titles from Olympia, which this year will be held from December 16-18 in Las Vegas, Nevada.

On his YouTube channel, Derek, like other athletes, posts his training videos. Recently he even added a brutal challenge that consists of 100 reps on the back squat with 315lb (142kg). However, his leg training didn't end there, he then went on to do leg press and leg curls on the machine. Those who would like to try Derek's full workout can get inspired below, but be cautious!
