Learn swinging on gym swing rings: hang, I, C+ and C− pose, forward and backward swing in pendulum rhythm, dismount and the hall's safety rules.
When you swing on the rings you hang from swing rings and build more swing with every forward and backward pass by stretching and curling your body in the rhythm of the pendulum. It is the entry to rings work and the base for turns, dismounts and everything that follows on the pendulum.
The honest answer to "How hard is it?": You need less strength than feel. The Swiss teaching material puts it this way: the art lies in raising the swing with every forward and backward pass. That only works if you settle into the rhythm of the pendulum, with relaxed shoulders and a long hanging body [1].
A classification first. This guide covers swing rings in the gym (long, free ropes). On competition rings something different applies: you start from a still hang, a coach is not allowed to give you an initial swing, and the arms should stay as straight as possible [4]. The swinging technique partly transfers but is not the same thing (TRANSFER).
Pull yourself into the straight I pose on the standing rings (shoulder, hip, ankle in one line). For ten seconds alternate lifting the shoulders ("short arms") and letting them hang ("long arms") [1]. Milestone: You find the long hang position without being told.
Stand in front of the rings, take an overgrip and place your feet one after the other at the lowest point. On the forward swing you push off with your feet [2]. Milestone: three small swings forward and back, braked in control.
Take a step forward under the suspension point, push the chest forward at push-off (C− pose) and at the end of the forward swing ("dead point") bring the feet forward-up (C+ pose, eyes on your feet, ears between your arms) [1]. Milestone: five forward swings with a clearly visible C+ at the end.
From the C+ you swing down-backward, the feet go back-up. The backward swing ends in the I pose or a slight C− pose, without a hollow back [1]. Milestone: five backward swings, back stays long.
The shorter the ropes, the shorter the time per pendulum: make movements quicker and smaller. With long ropes make them bigger and swing the legs actively, as if they had to clear an obstacle [1]. Milestone: Your swing volume visibly grows from pendulum to pendulum.
Try swinging with your eyes closed, but only small, with mats and a supervisor. The Swiss material recommends it for rhythm and body feel, orientation in space and depth sensitivity [1]. Afterwards you feel the dead point much more precisely once your eyes are open again.
By working in the rhythm of the pendulum: the time from push-off to the end pose has to match the time the pendulum needs to reach its turning point [1]. If you react too early or too late, you brake yourself.
Above all you need hanging strength and body tension [1][2]. For beginners: keep sequences short, no longer than 20 seconds, and start braking on your own when you get tired [1].
The easiest is the backward dismount: release at the dead point, bring the legs to the vertical, arms forward to the side, hips and knees cushion [1]. Land on a dismount mat with gym mats underneath [1].
Swing rings hang from long ropes and are made for swinging. On the competition apparatus you start from a still hang, the coach may not give an initial swing, and the arms should stay straight [4].
It depends on hanging strength and feel for rhythm. Many find the beat in a few sessions, a high, clean swing takes longer. That is an experience-based estimate, not a study figure.
