As part of a long WOD (workout of the day) last night, I did Manmakers. My version is a pushup with a side plank using dumbbells. Its similar to what you see in this video.
For me, the pushup was really easy. But the posterior deltoid work from the side planks was killer. I could totally feel it as I did it. More importantly, I can feel it today. I was trying to do some wall work rotating into a backbend. But my rear delts and infraspinatus kept cramping so badly. So I know they were worked really hard.
Add this amazing exercise to your workouts.
