Modified V-Ups
The modified V-up folds the body toward a V with bent knees — chest and knees rising to meet over the hips — trading the full version's long levers for a range every beginner can own. It teaches the simultaneous upper-and-lower fold that full V-ups will later demand at length. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.

Level — Beginner
Beginner — the coordination of the double fold is the lesson; the burn is the tuition.
Proper form — 5 cues
- Lie back with arms extended overhead and knees softly bent.
- Fold both ends at once — chest curling up as the knees draw in.
- Meet in the middle: hands reaching past the shins toward the ankles.
- Balance a beat on the tailbone at the top of every rep.
- Unfold with control, shoulders and feet hovering just off the mat at the bottom.
Breathing: Sharp exhale as the body folds to the V, inhale on the controlled unfold.

| Strength — standard | 4 | 5-6 paused at the top | 1-2-2-0 | 90 s | 7-8 |
| Strength — advanced | 4 | 6-8, 2 s pause, straighter legs | 1-2-3-0 | 90 s | 8 |
| Hypertrophy — beginner | 3 | 8-10 | 1-0-2-0 | 60-90 s | 7 |
| Hypertrophy — standard | 3-4 | 9-12 | 1-0-2-0 | 60-90 s | 7-8 |
| Hypertrophy — advanced | 4 | 12, no shoulder touch-down between reps | 1-1-2-0 | 60 s | 8-9 |
| Endurance — beginner | 3 | 12-15 | smooth continuous | 60 s | 6-7 |
| Endurance — standard | 3 | 15-20 | smooth continuous | 45-60 s | 7-8 |
| Endurance — advanced | 3 | 20 or 40 s continuous | brisk, form intact | 45 s | 8 |
| Beginner on-ramp — week 1-2 | 2 | 6, single-knee tuck version | slow, find the balance point | 90 s | 4-5 |
| Beginner on-ramp — week 3-4 | 2-3 | 8, both knees tucking | controlled | 60-90 s | 6 |
| Deload / technique | 2 | 8 easy tucks, exhale at the top | slow, no rocking | 60 s | 4-5 |
Common questions
What makes a V-up harder than a crunch plus a leg raise?
The simultaneity. Folding both ends at once removes every anchor — nothing is pinned to the floor to pull against — so the abs must both create the movement and balance the body through it. That coordination under load is the specific skill the V-up family trains.
When do I graduate to full V-ups?
When three sets of twelve modified reps feel crisp — both ends rising together, a still balance point at the top, controlled unfolds. Then straighten one leg at a time before attempting both, exactly as with leg-raise progressions. The lever doubles; respect the jump.
Why do I roll backward at the top?
The balance point on the tailbone is narrow, and folding unevenly — usually knees arriving early — tips you off it. Slow the fold, aim the hands at a fixed point past the shins, and shrink the range slightly until the pause at the top becomes still.
