reckonerShin-height step-up
A step-up onto something low. The height is the whole specification: no higher than mid shin, which keeps the rep inside a range almost anybody can control and stops it turning into a lunge at a step. It is where a step-up starts, not a lesser version of one.

How to do it
Find something solid at mid shin or below
A low box, a bottom stair, a sturdy step. It has to hold your weight without sliding or tipping. Step onto something no higher than mid shin, which is the cue on your wrist and is a limit rather than a suggestion.
Place one whole foot on it
The whole foot, close enough that your shin comes up near vertical. Hands free at your sides or lightly on a wall if you need the reassurance early on.
Push through the top foot to stand
Drive down through the raised foot until that leg is straight. The foot on the floor does not push. That is the difference between training the top leg and stepping up a stair.
Lower under control on the same leg
Come back down slowly and touch the floor lightly. Finish the reps on that side before you swap. If you are dropping off it, the height or the rep count is ahead of you.
What goes wrong
Pushing off the bottom foot
A small press from the floor makes every rep easier and hides that it did. Try starting each rep with the bottom toe already light, and if the rep will not happen without a push, the step is too high for now.
Going higher because it feels easy
The height is what makes this movement the one it is. Raising the box turns it into the dumbbell step-up, which is a separate movement with its own record here. If you want harder, get slower and get load before you get higher.
Underrating it because the step is small
A low step-up is still one leg lifting your whole body weight, and it is still a step-up. In a systematic review across sixteen studies, step-up variations produced the highest gluteus maximus activation of any exercise reviewed1. Small step, real work.
How Reckoner progresses this lift
Six weeks of this lift, run through the real engine. Nothing below was typed in: the prescription, the decision and the sentence beside it all come from the same code that writes your week.
| Week | Prescribed | What it did |
|---|---|---|
| 1 | 4 x 6 | More reps 6 → 7 repsYou finished every set at RPE 7, with room left in the range, so the reps climb before the load does. |
| 2 | 4 x 7 | More reps 7 → 8 repsYou finished every set at RPE 7, with room left in the range, so the reps climb before the load does. |
| 3 | 4 x 8 | More reps 8 → 9 repsYou finished every set at RPE 7, with room left in the range, so the reps climb before the load does. |
| 4 | 4 x 9 | More reps 9 → 10 repsYou finished every set at RPE 7, with room left in the range, so the reps climb before the load does. |
| 5 | 4 x 10 | Deload 40% of sets offFive weeks of building, then one week lighter. About 40% of the sets come off. The load holds and your reps stay where you earned them, so you keep the strength and lose the fatigue. |
| 6 | 2 x 10 | One more set 2 → 5 setsYou hit the top of the range at RPE 7 and there is no weight left to add. When a lift runs out of load, the set is the increment, so it does five sets next week. |

The full rule, and why the reps move before the load does, is in how Reckoner decides to add weight.
Questions people ask
Why is the height capped at mid shin?
Because above that most people stop pushing with the top leg and start hauling themselves up with the torso, and the exercise quietly becomes something else. Keeping it low keeps the work where it is meant to be.
How do I progress this?
Slower lowering and a pause at the top first. Then load: the library carries a vest step-up and a dumbbell step-up, both onto a box, and both are separate movements with separate records.
Will Reckoner take this out of my plan for an injury?
No. This is one of the few movements in the library with no restrictions recorded against it at all. That is a fact about the record rather than a clearance, and a specific injury is still a conversation for whoever is treating it.
Similar movements
There is no load to ease on this lift, so Reckoner offers one of these the first time it stalls. Each of them has a page.
