When Men’s Fitness approached Brad Schoenfeld, Ph.D. about the Justin Bieber exercise routine, his first reaction was “sounds to me like Justin Bieber would benefit from developing an overall structural foundation at this point.” Brad is a prolific exercise researcher, an assistant professor at Lehman College in New York, a natural bodybuilding champion, and author, most recently, of The MAX Muscle Plan.
“Ultimately you’d want to work through a spectrum of rep ranges, adding some low- and high-rep work to the mix,” he says. Low-weight/high-repetition exercises add to muscular endurance and can get the heart rate up to burn calories during weight training.
Brad also wants to see an overreaching phase—a period where you deliberately push your body as hard as you can—followed by a short deloading phase. That guarantees full recovery along with a mental break from the stress of all-out training. And because we all know that being a teen can be stressful enough, we at VarCity highly recommend taking break from any all-out training that you incorporate into your routine!
