The 1990 is a rotation on one hand in a handstand. Which base you need, what the build-up with a teacher looks like and how to protect wrist and forearm.
What is the 1990 and how do I build it up? The 1990 (also handspin) is a pro element in breaking: a rotation on one hand in a handstand. You stand in a handstand, only one hand carries, and the body rotates around that hand. It is one of the moves where the hand is axis, support and brake at once — which is why it is not for beginners.
The honest answer on learning time: whoever brings a free handstand and healthy wrists often needs many months to years for the 1990. That is practical experience, not a study. And: this guide is deliberately not an imitation manual. It explains what you must be able to do first and why supervision is part of the prerequisite.
Why the handstand matters so much: a systematic review of 21 studies shows that gymnasts maintain balance in the handstand mainly through the “wrist strategy”; only when that is not enough are shoulders, hips and elbows added. Stronger gymnasts also had better balance, and a flexed neck posture impaired handstand performance [1]. So in your 1990 the wrist is not one joint among many but the permanent workhorse.
Imagine a plate on a stick that you spin: the stick must stand straight or the plate falls. Your arm is the stick, your body the plate. In the 1990 it is not the rotation that decides between success and injury but whether the stick — hand, wrist, shoulder — is strong and straight enough beforehand.
Your free handstand must stand, and so must the headstand freeze. Without this base the hand rotation has no ground. Milestone: handstand 10–15 seconds free, three times in a row, without wrist pain.
Over months: grip strength, wrist flexion and extension with light resistance, support variations on the fingers, forearm mobility. This is a permanent programme. Milestone: you stay permanently pain-free in everyday life, even the day after intensive sessions.
Now comes the part no text replaces: a teacher shows you the weight shift onto one hand in a safe form, spots you, corrects hand and arm position and decides when you are ready. Anyone who cannot tell you how to get out of the position safely is the wrong teacher. Do not learn this step from videos, even if it looks easy in clips: the safeguarding is precisely what you never see.
Short attempts, long breaks, plan the exit, watch the wrist. Milestone: the teacher gives you the OK for single short attempts without help, and wrist and forearm stay pain-free.
The 1990 is a rotating element on one hand — that stresses wrist, ulna and shoulder. In a survey of 321 handstand practitioners 56.7% reported chronic wrist pain, more often in younger people [2] (TRANSFER: yoga, capoeira and movement, not breaking). In breakers wrists were affected in 57.7% [3]. A case report describes a stress fracture of the ulna in a breaker; according to the authors, ulnar stress fractures arise among other things from repeated excessive forearm rotation, and the X-ray was initially unremarkable [4].
For you that means: build-up over months, mat, teacher, short sessions. With pain, numbness or tingling in the hand stop immediately and have it checked. This guide does not replace supervised training.
Train forearm rotation away from the spin: gentle pronation and supination with light weight, grip variations, switching between hand positions. That is practical experience, not a study, and it fits the case report's warning about repeated forearm rotation [4]. If your forearm tires in everyday life, the 1990 is still too early. And a second rule of thumb: if you cannot change hand position without thinking, you still lack the hand control for a rotation.
Many months to years, depending on handstand, wrists and supervision. That is practical experience, not a study. Base and supervision matter, not time.
It loads wrist, ulna and shoulder considerably. Wrists were affected in 57.7% of Italian breakers [3]. With build-up, mat and teacher the risk falls; it never reaches zero.
Not as a substitute for build-up. In a survey of 321 handstand practitioners no significant links were found between chronic pain and warm-up, braces or grip devices [2]. Targeted strengthening and supervision make more sense.
The handstand spreads the weight over both hands; in the 1990 one hand carries alone, plus the rotation. That means more load per hand and more forearm rotation. How much more exactly has not been measured; so we treat it as clearly more demanding to be on the safe side.
Videos show the result, not the safeguarding. Use them to understand, not to rebuild alone. For the critical step a teacher is needed.
