I’m starting the year off with a few tests for my current strength training program. My Current Strength Training Every movement marked with (*) is performed for 1 set of 60 seconds to failure using accommodating resistance. Mobility movements, marked with (~), are performed for 2 sets of 30 seconds using contract-relax PNF stretching. The Kettlebell Swing is used exclusively for cardio, I perform 1 heavy set for 60s with the goal of reaching between 90 and 100 percent of my max heartrate (Zone 5).
