Martial artists and sport fighters with some level of experience are aware that some punches or kicks are stronger than others; some people just accept that as a fact, some of us try to understand the reasons behind by studying the human anatomy, how the body works and how biomechanics actually apply to these techniques.
If the first step in this process will help you understanding why things work in a certain way the natural evolution from there will be to better train the muscles involved in the movement and improve your performance.
Although different people will achieve different results when striking with various punches I will list below my 5 top favourite martial arts punches (e.g. not limiting ourselves to IBA boxing strikes):
I think of the jab as an amazing technique; when well trained it can be super fast, ideal to strike the opponent at both medium (abdomen, chest) and high level (face). In boxing (as much as in kickboxing) the Jab is very much the bread and butter of the fight, mostly used to strike often the opponent in order to check and maintain the distance and as a preparation for other more powerful, but often slower and more energy demanding, techniques. The Jab should always travel on a straight line, directly from your guard toward its target and then being withdrawn immediately to go back ready for the next strike. The total number of muscles involved in the jab is relatively small: mostly the triceps, with small contribution from deltoid, pectoral and trapezium. Extra power can be added with a well timed little step forward while some people add an extra torsion on their core to involve a few more muscles; I generally don’t as I find it time consuming and less easy to follow up.
It’s the most powerful punch I can throw, with either hand or from either stance, reason being the high number of strong muscle groups involved in the motion: the bicep, the deltoid, pectoral, some of the abdominals, good part of the core and, if well performed, the calf, quadriceps and the hip area. Although all hooks hits the target sideways in a circular motion, from a mechanical and geometrical point of view the hook performed with the leading (front) hand is totally different from the hook performed with the rear (back) hand. In the first case the only way of delivering power is to perform a counter turn that while shifting weight on the rear leg builds up momentum to be transferred to the arm and the fist. When striking with the rear leg it’s important to push from the rear leg, starting from the ball of the rear foot, twisting the hips forward in synch with the arm moving forward in the strike.
The Cross shares the simplicity offered by a straight trajectory similarly to the jab, but it develops more power for two main reasons: it travels for a long distance therefore it builds up more momentum, delivering more damage; it involves, on top of all muscles involved in the jab, the hip torsion (core, gluteus) and the push from the rear leg as previously described in the hook from the rear hand. Adding a little step even if moving just a few millimetres it can help to add a substantial amount of extra power.
The Back Fist
The Back Fist punch (as in the picture above) is a typical martial arts punch that derives from traditional styles like karate and kung fu; it was never part of the IBA boxing repertoire but, funny enough in the UK it is being progressively removed from various light and full contact kickboxing rules. The Back Fist is not a particularly powerful punch as it involves just triceps and the shoulder muscles; at the same it is very fast and annoying because it hits people on the side of the face or some times on the nose. Very popular in semi contact kickboxing it’s an ideal technique to be used while fighting in side stance and combined with side, round and hook kicks with the front leg.
The Spinning Back Fist
The Back Fist is the only punch that makes sense when performed while spinning back; while maintaining the limitations of being by its own nature a weak punch the spinning movement, if well performed and timed, can deliver an unexpected amount of power. The spinning should always being performed in a way that the eyes (e.g. your vision) hit the target before the punch, in short, look at what you are striking. The Spinning Back Fist was acceptable within kickboxing rules until a few years ago but it’s now been abolished in every style for its apparent lack of control and the amount of damage it can deliver when properly performed.
