If you want to build mass but are short on time, trust us: You're not alone. Thankfully, Perfomix athlete Andy Speer has provided us with a challenging routine you can finish in just a half-hour.


Perform this circuit for 30 minutes. Don’t rush. The weights should be a heavy working set of five reps, 75-85% of your 1RM. Perform once per week. Add five minutes each week for four to six weeks. Rest as needed.
