Technically Cardio is exactly what the fine print promises - seventy reps of continuous standing movement that raises your heart rate without a single jump, sprint or apology. Step half jacks three times, step backs twice, step bicep extensions twice: the entire cardio family tree, with every high-impact branch politely pruned.
The word technically is doing honest work, and so is the workout. Every exercise here is a stepped translation of something bouncier: step half jacks trade the jump for a wide step while one arm sweeps, step backs turn running into a controlled rearward reach of alternating legs, and step bicep extensions fold arm work into the footwork so the pulse keeps its lease. Nothing leaves the ground, which means nothing pounds the knees, ankles or downstairs neighbors - and yet seventy continuous reps of stepping, sweeping and reaching is, by every physiological measure that matters, cardio. The heart does not check whether you jumped. It only checks whether you moved.
Keep the steps wide and deliberate - a lazy shuffle converts this from technically cardio to technically standing. Sweep the arms through their full arc on the half jacks, reach genuinely back on the step backs with your chest tall, and keep the bicep extensions crisp at shoulder height while the feet keep time underneath.
No jumping, no pounding, no loopholes closed. The heart rate is up, and that is the only technicality that counts.
Make it Harder: Speed up every block while keeping the steps wide.
Make it Easier: Slow the pace and shrink the steps - it still counts.
