The handful of positions and movements every calisthenics skill is just a harder remix of. Not a separate phase — this is what Phase 1 is made of. Learn these primitives and the muscle-up, front lever, and handstand stop being mysteries.
The biggest thing beginners miss: calisthenics has two separate strength trees, and both grow out of the same small foundation. Most people only ever train one tree.
Every "skill" is just a harder rung on one of these trees, standing on the same body-line and scapular control. Nothing above is a new mystery — it's a remix of the primitives below.
Before any tree, the two reference shapes. Every calisthenics position is either a hollow (front side shortened, a shallow banana with the belly scooped) or an arch (back side shortened, the "superman"). Skills are just these two lines held under harder and harder leverage. If your body sags out of line, the skill collapses — so this is rung zero of everything.
| Shape | What it is | Drill it with | Watch |
|---|---|---|---|
| Hollow | Ribs down, low back pinned, body a shallow dish | Hollow hold → hollow rocks | ▶ |
| Arch | Glutes & back squeezed, chest & legs lift (superman) | Arch hold → superman rocks | ▶ |
The piece almost every beginner skips. Your shoulder blades (scapulae) have to move and then lock for anything overhead or hanging to work. Train them to depress/retract on a pull and protract/upwardly-rotate on a push, and two things unlock: your first real pull-up, and the entire straight-arm tree.
These are also two of the ★ prehab drills from the muscle map (serratus, lower traps) — so you're already meeting them in Phase 0. Here they get a job: the bridge between body-line and the trees.
The half you already know: six movement patterns, elbows bending, done for reps. This is the four ladders of Phase 1 (push, pull, legs, core) — listed here so you see it as one of the two trees, not the whole sport.
| Pattern | Entry move | Grows toward | Watch |
|---|---|---|---|
| Horizontal push | Push-up | One-arm push-up | ▶ |
| Horizontal pull | Bodyweight row | Front-lever row | ▶ |
| Vertical push | Dip / pike push-up | Handstand push-up | ▶ |
| Vertical pull | Pull-up | One-arm pull-up / muscle-up | ▶ |
| Squat | Bodyweight squat | Pistol squat | ▶ |
| Hinge | Glute bridge | Nordic curl | ▶ |
The half that makes calisthenics athletes look strong at every angle — and the part Phase 1 has to add. Arms stay straight; the load pours into the shoulders, scapular muscles, and connective tissue. It's mostly cool (control/isometric), but it builds serious tendon strength and is the direct base of the flashy skills.
| Hold | What it trains | Grows toward | Watch |
|---|---|---|---|
| Dead / active hang | Grip, shoulder decompression, scap pull | The pull-up + all hanging skills | ▶ |
| Support hold | Straight-arm lockout on parallel bars/dip station | Dips, L-sit, planche line | ▶ |
| L-sit | Compression, straight-arm support, core | V-sit, manna, planche | ▶ |
| Tuck planche | Straight-arm push lean (protracted scap) | Advanced tuck → full planche | ▶ |
| Tuck front lever | Straight-arm pull, hollow line horizontal | Advanced tuck → full front lever | ▶ |
| Wall handstand | Overhead line, straight-arm push, balance | Free handstand → HS push-up | ▶ |
The transition isn't a new start — each primitive becomes an entry rung, and the body-line/scap work becomes the quality standard threaded through every rep and hold. Here's the exact hand-off:
| Foundation | Becomes in Phase 1 |
|---|---|
| Hollow / arch body-line | The rigid shape inside every push, pull, hold — plus core-ladder rung 1 |
| Scap pull (from hang) | First rung toward the pull-up (pull ladder) |
| Scap push (from plank) | Quality inside every push-up; base of the planche line |
| Plank | Push-up (push ladder, rung 1) |
| Dead / active hang | Holds track, rung 1 · gateway to pull-ups |
| Support hold | Dips + the holds track |
| L-sit, tuck planche/lever, wall handstand | The straight-arm holds track (runs alongside the rep ladders) |
Phase 0 bulletproofs the joints → these primitives teach the shapes & the two trees → Phase 1 climbs both trees' ladders → Phase 2 adds the heavy force ceiling on top.
So in Phase 1 you run two tracks at once: the bent-arm rep ladders you already have, and the straight-arm holds track from tree two. The body-line and scap drills shrink into your warm-up and become the form check on everything above — exactly how Phase 0's prehab folded in.
| Layer | What & why |
|---|---|
| Body-line | Hollow & arch — the two rigid shapes every skill is made of. |
| Bridge | Scapular control — blades that move & lock; unlocks pull-ups + skills. |
| Bent-arm tree | Dynamic reps: push, pull, dip, row, squat, hinge. = Phase 1 rep ladders. |
| Straight-arm tree | Isometric holds: hang, support, L-sit, planche, levers, handstand. = the holds track. |
| Skills | Muscle-up, front lever, planche, handstand — just harder rungs, not mysteries. |
| The rule | Everything above stands on body-line + scap control. Own the shape first. |
