A Guide to Punching Bags

A.J. Liebling, who wrote The Sweet Science in 1956, was nostalgic for a time when neighborhood boxing clubs were common, before they were overtaken by family circle TV. I won’t go that far but I do happen to believe in the value of neighborhood boxing clubs as a venue to learn and grow, and also as an outlet to explode and work out the jitters. The heavy bag and the speed bag are the iconic pieces of boxing paraphernalia, but there are others, and the intent here isn’t to hand hold or bury you in information, but give a little history and perhaps inspire you to try these tools of the sweet science. (Note that this isn’t an endorsement of professional boxing, which I see as a mismanaged and crooked beast.)

THE STANDARDS

The speed bag and its smaller cousin, the peanut bag, are teardrop shaped and inflated — essentially leather-or-vinyl-covered balloons hung under a rebound platform by a short swivel which sends a punched bag quickly swinging back at you, and are designed to increase dexterity, endurance, timing and hand speed. Since it’s light and air-filled, risk of injury is low, and gloves or even hand wraps aren’t necessary.

The heavy bag is another gym fixture, with the 100-lb, pillar-shaped version running standard in gyms, though there are other shapes and sizes (Bruce Lee used one that weighed 300 lbs.). It may be tempting to just start wailing away on one of these, but this piece of equipment deserves some respect when working it. Since its point is to be heavy, lack of protection risks damage to the wrist or metacarpals.

Punching side note: this injury is referred to by doctors as a bar room or brawler’s fracture or lover’s fracture (after the spurned lover hits something, usually a tree or wall, in anger — yes, it happens often enough to get its own alias). However, boxers (as opposed to the spontaneously violent) know to wrap and protect their hands to avoid this particular injury. Cotton hand wraps are essential with heavy bags to keep your fist and wrist in line and, depending on the bag’s filling, I strenuously suggest using bag gloves as well.

THREE UNSUNG HEROES OF THE GYM

The reflex bag, slip bag and maize bag are used as much for defensive work as anything, and deserve some attention.

A reflex bag is a spring-loaded, floor-mounted speed bag that hits back. It improves hand speed, accuracy, defense, and is a hell of a lot of fun to work with. Hit fast, bob and weave, move your feet, don’t get whacked when it snaps back up at you… If I could only pick one, it might not be this piece of equipment but if you have access it is much harder than you might imagine, and risk of (hand) injury is low.

The slip bag is a homegrown item that is purely used to practice defensive head and body movement, i.e. avoiding, or slipping punches. Often no more than a sand filled sock on a rope, it swings back and forth at the head while the user works on movement and shadow boxes. A very low impact exercise, with cardiovascular value and no risk of hand injury, it was popularized by Mike Tyson’s trainer Kevin Rooney.

The maize bag. This is my personal favorite, combining the strength training of a heavy bag and some of the defensive challenges of the others. This rather shapeless bag usually weighs around 50 pounds and was traditionally filled with maize pellets, though now plastic granules are used as they won’t rot or attract weevils. (Lovely.) Hung from the ceiling by chains at chest/head height, it swings freely and lets the user duck, block, bump and clinch it as well as work on all manner of punches. A lot of foot work is required to follow the bag as it swings, and the granular nature of the filling and movement of the bag reduces the risk of hand injury, though hand wraps are recommended again to protect the wrist. The maize bag generally isn’t seen in health club gyms, but rather in boxing clubs or similar venues. Less expensive and a more practical option than the heavy bag.
