Pulse Lunge

The pulse lunge holds the bottom of a lunge and adds small repeated movements rather than standing back up between repetitions. Staying low is the entire mechanism: the quadriceps and glute of the front leg never get the brief unloading that the top of a normal lunge provides, so blood flow is restricted and metabolic stress builds quickly. It is a straightforward way to fatigue a single leg with no equipment at all, which is why it appears so often in home workouts and circuit finishers. The mistake that undoes it is letting the pulses grow into full repetitions, which reintroduces the rest you were trying to remove. Keep the range small, the front knee tracking over the ankle rather than past the toes, and the torso upright throughout the set. A set that looks trivial written down becomes genuinely demanding within twenty seconds, so judge it by how the leg feels rather than by the number of pulses you complete.
