1-2-Left Upper-2-3-2-Roll-2-3-2

This combination, 1-2-Left Upper-2-3-2-Roll-2-3-2, is a dynamic and sophisticated sequence that integrates foundational offense, a vertical assault to breach the guard, defensive evasion, and a powerful, rhythmic counter-offense finish, emphasizing continuous flow and leveraging defensive movement to set up return fire.

Phase 1: Foundational Entry (1-2)

The sequence begins with the most fundamental and effective two-punch combination in boxing, designed to establish rhythm and force the opponent onto the defensive.

• Jab (1): This is a quick, straight punch thrown with your lead hand. It is not a power punch, but serves as the setup, primarily used to measure distance, disrupt the opponent’s rhythm, and create an opening by forcing them to raise their guard. Mechanically, you rotate your front hip into your back leg and extend your front hand straight down the middle, aiming for about 90–95% extension.
• Straight Back Hand (2): Thrown immediately after the jab, this is the power punch of the combination, delivered with the rear hand. Its force is derived from the rotation of your hips and torso.

Phase 2: Vertical Assault and Pressure (Left Upper - 2 - 3 - 2)

This quick sequence exploits the opening created by the initial entry, attacking vertically and then horizontally to maintain pressure. The "Left Upper" refers to the Front Uppercut, thrown with the lead hand.

• Left Upper (Front Uppercut): Thrown with the lead hand, this punch is designed to come "up the middle" and break through a tight guard. As it lands, it is disorienting and forces the opponent to raise their guard even higher, creating further openings.
• Straight Back Hand (2): This is a rapid continuation of the sequence, maintaining pressure. It is a power punchleveraging the rotation of the hips and torso, thrown to catch the opponent as they adjust to defend the preceding uppercut.
• Front Hook (3): This lead-hand hook follows the straight and is used to establish rhythm and attack from an angle the opponent isn't expecting. Proper execution involves focusing on extending fully by aligning the elbow with the wrist and letting the shoulder blade rotate.
• Straight Back Hand (2): A rapid continuation of the sequence, used to maintain pressure on the opponent.

Phase 3: Defensive Evasion and Coil (Roll)

After the offensive burst, this crucial defensive movement anticipates and evades the opponent’s likely counter while simultaneously generating energy for the next phase.

• Roll: You anticipate the opponent’s counter (often a straight punch) and execute this defensive head movement by moving your head off the centerline. It is performed by bending your knees and lowering your level. This is a critical movement because it loads your hips and core, coiling your body like a spring for the next attack.

Phase 4: Counter-Offense Finish (2-3-2)

This powerful sequence capitalizes on the stored momentum from the roll and the opponent's vulnerability from their missed counter.

• Straight Back Hand (2): This counter-offensive shot is fired immediately as you come out of the roll. The body’s momentum from the Roll transfers directly into this shot, giving it extra snap, as the opponent’s defense is compromised from their missed counter.
• Front Hook (3): This punch follows the straight, attacking from an angle the opponent isn't expecting.
• Straight Back Hand (2): The combination finishes strong with a final power punch. This punch is thrown to catch the opponent as they turn or adjust to defend the preceding hook, leveraging momentum to generate rotational force and conclude the sequence with authority.

This combination acts like an advancing spring: the initial punches compress the opponent's defense and load the coil (Roll), which then explodes into a powerful, rhythmic counter-attack (2-3-2).
