Develops Strength and Power The heavy bag was initially invented so that boxers could hit something with full force without breaking it or injuring their hands. This remains the main characteristic of the heavy bag. It develops punching power and strength. Pummeling the bag repeatedly builds strength and density to the muscles, bones, and ligaments of the body and conditions the body to the overall impact. Enhance your Stamina and Endurance If you think you are in good fighting shape, try blasting the heavy bag a full 3-minute round with max power. You will be surprised at how quickly you will fatigue. Our Muay Thai Heavy bag is one of the best training tools to develop endurance and stamina to achieve your training goals. Convenience For most martial arts training, you need a partner or a trainer. On the other hand, the heavy bag is excellent as a solo training tool. A great convenience is that if you have some small space in the garage or basement, you can install a bag and train without needing a gym or a partner. Going to a training session at a fixed hour is not always possible, but the bag will always be at your disposal. All In One Training There is no other tool that helps you hone your technique while building the physical attributes simultaneously. Strength and conditioning and technique drills are very important to be done separately, but heavy bag training combines both in a single exercise.
