So I'm new to Masters (few months) and fairly new to swimming (few years). I keep up fine at Masters practice with freestyle in my usual (second slowest) lane. Wanting to add butterfly so I can do IM parts of practice. As I do some basic beginner's drills, will my fairly short training fins help me to get a better feel for stroke and dolphin kick, or just lead to bad habits? And if using a board to build up endurance on dolphin kick, any tips on getting downward chest action involved while using board? I'm guessing my current dolphin kick is very hip/knee driven. Thanks!
