The bob and weave is a great exercise to practice defense and slipping/ducking punches. A good visual is to imagine a rope tied off at head height. Make sure to bob and weave under the rope and avoid hitting the rope with your head. Start in an athletic fighting stance. Envision your opponent throwing a punch at you as you slip each attempted shot. Bend your knees slightly and bob under the imaginary punch, dropping your center of gravity, keeping your guard up. Quickly return to your upright boxing stance. Continue bobbing and weaving, back and forth, as if your body is following along the path of a “U” shape for the remaining time. Rest for 10 seconds. Repeat x 3.Key point: Keep your hands up in a guard the entire time. Added challenge: Switch your stance halfway through.
