Key equipment you should have in your gym
Heavy Training Bag
A heavy bag is the first piece of equipment you need and it is the best training tool you could ever have. It helps develop technique, power, and speed of both kicks and punches.
Traditionally, bags are a large cylinder shape but sometimes they were man-shaped with stuffed arms and legs. Sometimes a stuffed leather self-righting bag was used that was similar to a self-righting inflatable punching toy used by children.
Purchased. You may find heavy bags at sporting good stores or online. Some bags are designed for boxing while others are designed specifically for martial arts training. Since boxers wear boxing gloves when punching the bag, boxing style bags tend to be hard, while martial arts bags are softer so as not to damage the hands and wrists.
Bags may be made from heavy vinyl (cheaper), rip-stop vinyl that resists rips (more expensive), or leather (most expensive). The more expensive bags come in more shapes and sizes. Some bags have a water-filled core that adds more weight. Some bags have an inflatable core to make them more resilient.
