Why five careful repetitions beat twenty quick ones
People who come to Pilates from the gym often feel short-changed in their first class. They are used to sets of twelve or fifteen, and here the teacher says "one more" after the third repetition and moves on to something else entirely. It looks like the easy option. It is closer to the opposite.
The low numbers are written into the method. In Return to Life Through Contrology, the 1945 book Joseph Pilates wrote with William John Miller, most of the mat exercises come with small counts, commonly three to five repetitions. The same book tells readers to concentrate on doing the movements correctly every single time, because a movement done badly loses its value. Read together, the instruction is plain: a few repetitions, each one done properly.
Why the numbers are small
The first reason is structural. A classical mat session is a sequence of many different exercises, and the volume comes from variety rather than from grinding out one movement. Flexion, extension, rotation, side work, rolling and balance all get their turn, so no single muscle group is driven to failure, yet the whole session still adds up to real work.
The second is fatigue. As a muscle tires, the body finds other ways to finish the job. In the Roll Up the neck starts pulling and the feet lift. In leg work the lower back arches to help. Momentum quietly replaces control. Twenty Roll Ups often means ten decent ones followed by ten rehearsals of the compensation, and the body gets better at whatever you repeat, errors included.
The third is attention. Precision needs concentration, and concentration runs out. Most people can hold a detailed picture of a movement in mind for five repetitions. Very few manage twenty. When the mind drifts, the movement drifts with it.
None of this makes high repetitions wrong. Endurance training, strength programmes and rehabilitation all use them deliberately, and if a physiotherapist has given you a set number for an exercise, stick to it. Pilates made a different trade, on purpose.
The same logic runs through a ballet class, where a combination is done once or twice on each side, carefully, before the class moves on. It may be one reason the method has drawn so many dancers into teaching. Christina Maria Gadar, a former ballet dancer, runs Gadar Pilates in Sarasota, Florida, and she is one of a long line of them.
The principles behind the counts
Joseph Pilates did not leave a numbered list of principles. The familiar six, usually given as concentration, control, centring, precision, breath and flow, were first set out as a list by Philip Friedman and Gail Eisen in their 1980 book The Pilates Method of Physical and Mental Conditioning. Both had studied with Romana Kryzanowska, and their list has been repeated, reordered and extended by training schools ever since.
Low repetitions are where those words stop being abstract. With only five tries you cannot coast through the first three. Control matters because there is no momentum to lean on. Precision matters because each repetition is a fifth of the total. Pilates framed the goal as coordination of body and mind, an idea explored in our piece on complete coordination of body, mind and spirit, and counting low is one of the most practical ways to train it.
What one excellent repetition looks like
Take the Roll Up. Lie on your back with the legs long and together and the arms reaching up towards the ceiling. Breathe in as the chin nods gently towards the chest and the upper back begins to peel away from the mat. Breathe out as you keep curling forward, one vertebra at a time, legs heavy, until you are folded over the legs with the abdominals still drawn in. Then reverse it: breathe in as the pelvis curls under and the lower back begins to roll down, and breathe out as the middle and upper back follow, the head and arms arriving last.
A good repetition is even in tempo, with no jerk at the hard bit, which for most people is the moment the lower back has to leave the mat. The feet stay down without being forced. The shoulders stay away from the ears. The return is slower than the rise.
If you need to bend the knees, or hold the backs of your thighs to get past the sticking point, do that. A supported repetition done well teaches more than an unsupported one done with a lurch.
Five exercises, five good repetitions
| Exercise | Usual count | A careful repetition | The usual shortcut |
|---|---|---|---|
| The Hundred | 100 beats, 10 breaths | Pumping arms, still trunk, gaze towards the stomach | Neck straining, legs dropping, back arching |
| Roll Up | 3 to 5 | Even tempo, one vertebra at a time | Throwing the arms, feet lifting |
| Single Leg Circles | 5 each way | Circle drawn from the hip, pelvis still | Circles so big the pelvis rocks |
| Rolling Like a Ball | 5 or 6 | Same tight shape throughout, a pause in balance | Kicking the legs to roll back up |
| Spine Stretch Forward | 3 to 5 | Sitting tall first, then curling forward | Collapsing forward from the hips |
How to practise this way
A short checklist for mat work at home or in class:
- Decide the number before you start, and stop there even if you feel fresh.
- Set up each repetition before it begins: breath, ribs, pelvis. Our guide to the three anchors of the pelvis explains the triangle teachers use for that last check.
- Make the return slower than the effort. Lowering is where control shows.
- If repetition four is worse than repetition two, stop at three next time.
- Take a breath between repetitions if you need it. Flow can come later.
- Progress quality first (more range, less help, smoother transitions) and add new exercises second, which is how good teachers think about progression anyway.
Tomorrow, do the Roll Up three times and make the third the best of the three. If it isn't, three was your number, and that is useful to know.
