Hard Strikes is an outrageous Cathe Friedrich boxing-infused cardio workout DVD that mixes basic boxing combos with intense cardio work. The punching combos are fun and easy to learn, but by no means easy to do. Some kickboxing is included in this section but the primary focus is on boxing. Once the cardio segment is complete, you'll continue with boxing specific conditioning drills that will make you look and feel like a champ. A bonus heavy bag section is included with the premixes for this workout to enhance your boxing experience as well as give you the means to strike even harder and more effectively.
