reckonerDumbbell step-up
Put one foot on a box and stand up on it. Simple to describe and easy to cheat, because the leg still on the floor can do most of the work without you noticing. Done honestly it is one of the most demanding things in the library for the glutes.
Push through the top foot to stand.

How to do it
Pick a box you can reach without lurching
Knee height is a good default. High enough to be work, low enough that you are not throwing yourself at it. Make sure it will hold your weight and the dumbbells, and that it will not slide.
Take a dumbbell in each hand and set one foot on the box
Whole foot on, not just the toes. Stand close enough that your shin is roughly vertical when the foot is up there.
Push through the top foot to stand
That is the cue on your wrist, and it is the entire exercise. Drive down through the foot on the box until that leg is straight and you are standing on it. The bottom leg does not push.
Lower under control, same leg
Step back down slowly and touch the floor with the bottom foot without putting weight on it. Finish the reps on that side before you swap.
What goes wrong
Pushing off the trailing foot
This is the fault that hollows the exercise out. A small push from the floor makes every rep noticeably easier and it is nearly invisible, including to you. Try touching the trailing toe down without pressing, or start each rep with that foot already off the floor.
Choosing a box that is too high
Above knee height most people start leaning forward and pulling themselves up with the torso, and the top leg does less rather than more. If you have to lurch to get up there, lower the box and add weight instead.
Filing it as a warm up
In a systematic review of gluteus maximus activation across sixteen studies, the step-up and its variations sat at the top of the list, above the hip thrust and the conventional deadlift1. It deserves a place in the session where you are still fresh.
How Reckoner progresses this lift
Six weeks of this lift, from 16 kg, 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 at 16 kg | 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 at 16 kg | 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 at 16 kg | 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 at 16 kg | 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 at 16 kg | 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 at 16 kg | Load up 16 kg → 18 kgYou hit the top of the range at RPE 7, so the bar goes up 2 kg to 18 kg and reps reset to six. The lighter week is over, so this is back to four sets. |
Real engine output, not an illustration. Every row was produced by running the engine itself when this page was generated.
The full rule, and why the reps move before the load does, is in how Reckoner decides to add weight.
Questions people ask
How high should the box be?
About knee height. That is high enough to demand real work from the top leg and low enough that you can get up there by pushing rather than by lunging at it.
Do I have to step back down slowly?
It is worth it. The lowering is free training you have already paid for by getting up there, and dropping off the box gives it away. It also stops the descent being a small impact on a straight leg every rep.
Will Reckoner give me this with a knee restriction?
No. Knee is the one restriction recorded against it, and unlike most of the leg movements it records no hip restriction.
Similar movements
Reckoner eases the load first when this lift stalls, and offers one of these only if it stalls again after that. A lift already as light as your kit goes has no load left to ease, so the offer comes straight away. Each of them has a page.
