Application & Execution
A punch is a penetrating attack on the opponent. Knuckles should be conditioned enough for effective results. A punch should be thrown like an arrow, straight and piercing. Relaxation of muscles is very important to execute a powerful punch, along with the use of the correct muscles.
- Maintain correct posture
- Engage hips and core for power
- Relax muscles before impact
- Tighten fist at the last moment
Muscles Involved
- Triceps
- Latissimus dorsi
- Pectoralis major
- Deltoid anterior
- Forearm extensors
Deltoid anterior – one of the key muscles engaged in extending the arm forward during a punch
Latissimus dorsi – critical for generating pulling power and stabilizing the torso during the Tsuki (punch)
Conditioning the Punch
Push-ups will help to condition triceps. A large variety of exercises can be done to condition, such as weight lifting exercises, lateral resistance band pulling, chest press, bench press, resistance band pulling or dip push-ups.
- Push-ups for triceps strength
- Bench press & chest press for pectorals
- Resistance band pulls for lat activation
- Dip push-ups for overall power
- Chishi and knuckle push-ups for forearm toughness
