This workout is so simple, but so...spicy. You don't need any equipment except maybe a table or chair if you want to make the bodybuilders easier. On the 8-count bodybuilders, don't rush. These are NOT burpees -- each pushup should be done perfectly and with control. When you're in the plank position and jumping your feet out, stay STABLE. Don't sacrifice form.
As you move through, breathing will be a factor ... BREATHE through. Pushup fatigue will come, and that's ok -- manage the fatigue, slow down the pace... but KEEP MOVING.
