Hi Joseph! A detailed description of the drills can be found on the workout glossary page. Human stroke is basically freestyle with underwater arm recovery (sort of like dog paddle with face in the water and breathing every 3rd stroke, keep a steady kick). Cobra breaststroke is breaststroke arms with freestyle kick. Have fun!
