This Monofin is great for developing a Rapid Butterfly Kick while building core strength.  The short and stiff fiberglass blade allows you to simulate race pace with a quick and powerful butterfly kick.  The shooter is great for working core muscles including abs, lower back, quads and gluts.  It is ideal for butterfly training to maintain a strong, composed stroke.  The shooter is also great for developing a powerful dolphin kick that is generated from the hips.  20" x 18" fiberglass blade.
