Reversibility is the ability to stop, start, and change the direction of a motion at any point in time.
According to Moshe Feldenkrais, the ability to perform reversals is a key indicator of well-organized, refined movement. When performing a movement, consider your ability to turn around and go the other direction, pause, or do something else. When our reversibility is impaired, it indicates a lack of freedom to change our minds or to respond to changing circumstances. This can be evident in certain functional movements: can we sit down in a chair or get on the floor slow and controlled, or is there a plop? When attempting to change the direction of a movement (e.g. pelvic clock circles), are we able to find a flow or is there jerkiness and incoordination? Can we walk backwards?
Reversibility is not just a movement, but a state of existence.
Our ability to be spontaneous, go with the flow, adapt, maintain presence and freedom of choice. An ability to perform reversals indicates that we are not moving on autopilot, but have a keen sense of what and how we are doing something in the present moment. When we reverse, we are traveling the same territory but from a flipped perspective. In the muscular system, what primarily for a particular muscle or muscles has been a concentric action (muscle shortening under tension) will become an eccentric action (muscle lengthening under tension). As mentioned above, “sit to stand” is a concentric action, and “standing to sitting” is an eccentric action. When we purposefully choose to reverse, it provokes the cognitive process of attentiveness, comparing and contrasting. This is one of the key requirements for learning.
When we use movement to enhance our learning, the quality of our lives can expand.
As we go through life, there may be a gradual tendency towards settling into our habitual patterns, and an associated loss of spontaneity, functional mobility, and options for how we move and engage with ourselves and the world around us. We may not be able to respond as quickly to the demands of the situation, like needing to step back quickly to avoid an oncoming vehicle while crossing the street. Or we may lose the agility required to turn around when we forgot our keys, and instead of taking one step backwards, we may need to take several small steps to turn ourselves around. The person who has difficulty with these reversals is much more vulnerable to falling when they do have to turn around quickly. Practicing reversals helps us learn more about how we move, and can expand our movement repertoire so we have more options available to us. We certainly do not want our only option to be able to plop down into a chair each time, rather than gracefully descending in any way we choose. Reversals are a key requirement for developing and improving balance, agility, neuromuscular control, and eccentric strength. In fact, dynamic balancing is essentially reversals in action.
Practicing reversals
Walking backwards
Walking backwards is a task that may have originally been easy, but perhaps can become impaired over time. If unsteadiness is present, perform this practice next to the kitchen counter or back of the sofa to have something to hold on to as needed.
Simply start by walking forwards slowly, paying attention to how your body moves, how the feet make contact with the ground, etc. Then, reverse it. Walk backwards, comparing and contrasting this experience to walking forwards.
Check out this article that dives into the health benefits of walking backwards.
Focus on the eccentric
Bring attention to the lowering component of a movement, whether this is in strength training or daily life.
A simple example is to practice standing up from a chair, paying attention to how you do this. Then, try to sit down the same way in reverse, challenging yourself to lower down slowly. Compare and contrast the process of standing and sitting in terms of the mechanics of the movement as well as the sensory experience.
If strength training is part of your routine, pay attention to the lowering movement such as the descent into a squat, the lower of the weight during a bicep curl, or the lowering of your chest towards the ground during a push up. Try to refine the control of the movement, with the ability to slow it down, pause it at any moment, or reverse the movement at any point in time. Also, in a safe manner, practice some reversals quickly, because sometimes that is what life demands!
Yoga Transitions
If yoga is part of your routine, tune in to the transition between two poses.
A simple example is cat and cow, which involves reversing between spinal flexion and extension. Tune in to the exact moment of transition, and explore reversing the movement at different speeds, and at different phases of the motion (e.g. can you do the cat cow in slow motion, and switch between cat and cow through variety of ranges, rather than going all the way into the full expression of cat pose before transitioning into cow?)
This can be applied to any transition in yoga (or life off the mat). Get creative with it- pick any two yoga poses, and explore a variety of transitions between the two shapes.
Explore Your Own
Enhance your sense of spontaneity and exploration by bringing reversals into your daily life.
Perhaps make up a dance move. Practice the move again and again. Then, try reversing the move, as if someone recorded you and played it in rewind. Or, take an everyday task. Reaching for a glass. Can you pause as you reach, and reverse it? Repeat this, reversing the movement at various stages of the reach.
Notice if this brings any greater sense of awareness of your movement and ability to choose different options for how to reach for something. And notice how much more confident you will be crossing a street when an unexpected vehicle requires you to take a very quick step backwards.
