3-2-1 Plank (Exercise of the Week #4)

If you can already do a basic abdominal plank for 30 seconds, challenge yourself beyond the basic plank instead of boring yourself with redundant exercises; spend that valuable (and limited) training time doing more advanced plank variations like the Performance U 3-2-1 abdominal plank, which combines a one-arm planks with a long-lever elbows plank: each held for 10 seconds each, two times through, totaling one-minute.
