The 'impossible dip' is an advanced bodyweight pressing exercise — a deep dip variation typically performed on parallel bars where the body is lowered to extreme depth (significantly below parallel) before pressing back up. The name reflects the demand: most trainees can't perform a single rep, and even advanced calisthenics athletes typically manage only 1-3 strict reps per set. The extreme depth is what makes it 'impossible.' Standard chest dips stop when the upper arms are roughly parallel to the floor. Impossible dips continue beyond this point, sometimes reaching positions where the shoulders are well below the elbows. The depth concentrates extreme load on the chest, anterior delts, and triceps in a position where leverage is at its worst. Like other extreme calisthenics variations, this exercise rewards patience and respects shoulder mobility. Trainees attempting it without sufficient prerequisites typically end up either failing the rep or developing anterior shoulder issues. Reserved for advanced athletes with the demonstrated mobility and strength, impossible dips can add unique pressing development that standard variations don't provide.

Why train the Impossible Dips?

Builds extreme pressing strength with unique loading pattern.
Develops shoulder mobility through extreme depth.
Provides advanced calisthenics goal.
Carries over to advanced gymnastics movements.
Once mastered, makes standard dips feel trivial.
Requires only parallel bars.

How to do the Impossible Dips: step by step

1Position yourself between two parallel bars with your arms fully extended and your body suspended in the air.
2Bend your knees and cross your ankles.
3Lower your body by bending your elbows until your upper arms are parallel to the ground.
4Pause for a moment, then push yourself back up to the starting position by straightening your arms.
5Repeat for the desired number of repetitions.

Common mistakes to avoid

Attempting without sufficient shoulder mobility
The extreme depth requires shoulder mobility most trainees don't have. Without it, the exercise causes anterior shoulder injury.
Skipping prerequisite work
Don't attempt impossible dips without 15+ strict standard chest dips, weighted dip experience, and demonstrated extreme shoulder mobility. Most trainees never need this exercise.
Letting the elbows flare wide at depth
At extreme depth, wide elbows concentrate load on vulnerable shoulder structures. Keep elbows tracking close to the ribs.
Performing them with cold shoulders
The position needs extensive warm-up. Spend 10+ minutes on shoulder mobility before the first set.
Programming high frequency
The shoulder demand requires extensive recovery. Once per week maximum, even for advanced trainees.

Easier and harder variations

Easier

Standard chest dips with conventional depth. Weighted standard dips. Or partial-range impossible dips (gradually increasing depth over weeks).

Harder

Add weight (a vest). Slow the tempo. Or progress to ring impossible dips (extremely advanced).

Alternative exercises

Standard chest dip
Conventional depth dip variation. The default for almost all trainees.
Weighted dip
Progressive overload through weight rather than depth. Safer for the shoulders.
Korean dip
Different specialty advanced dip variation that emphasizes shoulder mobility differently.

How to program the Impossible Dips into your training

Impossible dips are extreme specialty work. Most trainees never need them. Sets and reps: 3-4 sets of 1-3 reps with 2-3 minutes rest. Total weekly volume of 4-12 reps for advanced trainees. In an upper body session: 3 sets of 1-2 impossible dips (specialty work), 4 sets of 8 standard dips (main pressing), 4 sets of 8 pull-ups (balanced pulling). Do not program impossible dips for general fitness. Reserve for athletes specifically pursuing advanced calisthenics goals.

Recovery and frequency

Impossible dips are extremely demanding on the shoulders. 72-96 hours between sessions is the minimum.

Frequently asked questions

How many sets and reps should I do?

3-4 sets of 1-3 reps with 2-3 minutes rest.

How often should I train this?

1 time per week max with 72-96 hours of recovery.

Are impossible dips bad for the shoulders?

For trainees without proper progression and mobility prerequisites, yes — they cause real shoulder injuries. For very advanced trainees with the proper preparation, they build extreme depth pressing strength.

Should beginners attempt impossible dips?

No — they're vastly overkill. Most trainees never need them. Standard chest dips and weighted variations cover all general training needs.

How deep is 'impossible'?

Significantly below parallel — typically with the shoulders well below the elbows at the bottom position. Standards vary; the defining feature is depth beyond what's normally considered safe.

Why are they called 'impossible'?

Most trainees can't do a single rep, even those who can do 15+ standard chest dips. The combined depth and load make the exercise prohibitively difficult for most.
