Day 43 puts the punch chain in front of the doubled kick. Four 15-second intervals - jab, cross and double side kicks on the right leg, double side kicks on the right, then the same pair on the left - three to seven sets, one minute of rest. The x2 marker sits beside the kick illustration, as it has since Day 19.
This is the longest string the program has asked for so far: two punches followed by two kicks from the same leg without the foot touching down. Four strikes in one cycle, and the whole thing has to flow. The punches build the rotation, the first kick spends it, and the second kick has to be generated from a standing position that is already leaning away and already tired. Following that with an interval of doubles alone removes the punches and leaves you with nothing but the hardest part.
Throw the punches sharp and short so you arrive at the kick with your balance intact rather than overcommitted. Chamber high, extend to the side, pull the foot back to the chamber and fire again. Guard up, standing foot pivoting, torso angled but controlled.
Four strikes, one cycle, one foot in the air for half of it - the chain is getting long.
Make it Harder: Add a return jab after the second kick so every cycle opens and closes with your hands.
Make it Easier: Run the combination as jab, cross and a single side kick, and keep the doubles for the second interval only.
