Arm Workouts

I tried a set today that was recommended to me by Paul Carter recently to improve my arm position. By swimming with my fists closed I'm forced to focus on how much water I'm catching with my forearm. It really is amazing how little water I pull with my arm. After a quick comparison of swimming with my hand fully open compared to closed fists it seems like I could do a better job with my arm positioning. I'll probably do this set more often, it seems like it helps me feel the water more.
