Dip Station & Parallettes

Both are parallel-bar tools, differing mainly in height.

• Dip station / parallel bars: waist-to-chest-height parallel bars for dips (chest and triceps) and support holds. Often built into a power tower with a pull-up-bar and captain's-chair pads for hanging knee raises.
• Parallettes: low (a few inches to ~1 ft) mini parallel bars used for L-sits (l-sit-progression), tuck/planche work, deficit push-ups (extra ROM), and handstand/HSPU practice (handstand-progression). The neutral grip and raised hands are gentler on the wrists than floor work, and the elevation lets the feet/hips clear the ground.

Pros: neutral grip (wrist/shoulder-friendly), portable (especially parallettes), open the push/static-hold side of calisthenics that a pull-up bar alone can't.

Cons / caution: dips put the shoulder into a deep, loaded position — going too low risks shoulder strain; keep depth to roughly upper-arm-parallel and control the descent (see dips-shoulder-hyperextension). Rings (gymnastic-rings) add instability for a harder progression.

• Dip bars (tall): dips, support holds; often part of a power tower.
• Parallettes (low): L-sits, planche/tuck work, deficit push-ups, handstand practice.
• Neutral grip is wrist/shoulder-friendly; parallettes are highly portable.
• Limit dip depth (~upper-arm parallel) to protect the shoulder.

• dip-progression — the dip skill.
• l-sit-progression — parallettes are the classic L-sit tool.
• handstand-progression — parallette HSPU/handstand work.
• gymnastic-rings — unstable progression of the same patterns.
• dips-shoulder-hyperextension — dip-depth shoulder caution.
