Inchworm to Low to High Plank (Modified)
The knees-down version of the inchworm with plank transitions: walk the hands out, drop the knees, perform the forearm-to-palm up-downs from the shortened lever, and walk back. It exists as the honest bridge for anyone not yet strong enough to keep hips level in the full version. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.
Muscles worked
Sets & reps by goal
| Goal | Sets × Reps | Rest |
|---|---|---|
| Strength | 4 × 4–6 sequences | 90 s – 2 min |
| Muscle | 3–4 × 8–12 sequences | 60–90 s |
| Endurance | 3 × 12–16 sequences | 45–60 s |

Level — Beginner
Beginner — deliberately easier on the trunk so the pressing pattern can be learned properly.
Proper form — 5 cues
- Walk the hands out as far as a straight body allows, then set the knees down softly.
- From knees, lower to the forearms one arm at a time — no flopping down together.
- Press back to the palms one hand at a time, keeping the hips still despite the shorter lever.
- Lift the knees before walking the hands home, so the return trip still trains the trunk.
- Alternate the leading arm every rep; symmetry now saves imbalances later.
Breathing: Breathe out with each press up to the palms; in as you lower to the forearms.
The 3 mistakes Maddy corrects most
Common questions
When do I move from this to the full version?
When you can complete three sets of ten sequences with zero hip sway and no long pauses, test two or three full-lever reps at the start of a fresh set. Progress rep by rep — full-lever first while you are strong, kneeling to finish the set — until the whole set converts.
Is the modified version still worth doing on its own?
Absolutely. The pressing pattern, shoulder loading, and transition mechanics are identical to the full movement; only the lever is shorter. Plenty of trainees keep it in circuits permanently for higher-rep work, using the full version separately for lower-rep strength sequences.
Why do my shoulders burn more than my abs here?
Because with the knees down the trunk demand drops sharply while the arms still perform every up-down. That is by design at this stage. As you graduate toward the straight-leg version, the ab and shoulder work rebalance and the trunk claims its share back.
