Steps
- Adjust a bar in a Smith machine to an appropriate height. Position yourself under the bar, racking it across the back of your shoulders. Unrack the bar, and then split your feet, moving one foot forward and one foot back. This will be your starting position.
- Lower your back knee nearly to the ground, flexing the knees and lowering your hips as you do so.
- At the bottom of the descent, immediately reverse direction. Explosively drive through the heel of your front foot with light pressure from your back foot. Jump up and reverse the position of your legs.
- Repeat for the recommended amount of repetitions.
Tracking it in OneRep
Add the lunge sprint to a routine and your previous weight and reps sit beside every set, so the decision to add load is made by what is already on the screen rather than by memory. Exercise history and volume trends are one tap away, and logging works offline for the gyms where signal does not reach.
Because OneRep tracks food on the same timeline, a stall on this lift can be read against what you were actually eating that month — which is the difference between a programming problem and an eating one. More on that in tracking progressive overload without a spreadsheet.
Where the instructions come from
The steps above come from free-exercise-db, a public-domain exercise dataset. They are general guidance, not coaching for your body: if a movement hurts, stop and get someone qualified to look at it.
