Sculling - moving your hand back and forth in the water, at your hips, your shoulder or over your head to keep your body balanced in the water while providing some propulsion. More specifically, this means to gently propel yourself through the water by moving your hands close to and just under your hips, using the figure-eight pattern. Basically, just easily push yourself through the water on your back.
Kenyan Running - lean forward, roll off your big toes, keep hand above your waist, look about 6 feet in front of you with your eyes, drive your elbows back and never cross your midline with your hands.
Use this day to also get additional 'Core Strength' exercises in for a total of 2-4 sessions per week. See Core and Strength Guidelines for more information.
