Pilates Movement Monday: Leg Springs on the Cadillac

One of the exercises that always reminds me how clever the Pilates apparatus is would be Leg Springs on the Cadillac. At first glance it looks quite simple. You are lying on the table, your feet are in the straps, and the springs are helping to support the legs. But anyone who has actually done the exercise properly knows there is much more going on.

The Cadillac, originally called the Trapeze Table, is designed to challenge the body in very subtle ways. With Leg Springs, the resistance is coming from above, which already changes the way the body has to organise itself. The springs want to pull the legs up, and that means the centre of the body has to work quietly but constantly to keep the pelvis stable.

The starting position is quite straightforward. The client lies on their back with the head close to the uprights and the arms reaching overhead to hold the vertical poles. The feet are placed into the straps attached to the leg springs. The legs lift away from the table, usually to around forty-five degrees, with the spine long and the pelvis in a neutral position.

From there the movement begins. The legs might lower and lift, open and close, or move into small circles. The patterns themselves are not the most important thing. What really matters is that the movement is coming from the hip joints while the pelvis stays quiet and stable on the table.

This is where the exercise becomes interesting. The springs are providing assistance, but they are also creating resistance and direction. If the body is not organised well, the pelvis will start to tilt, the lower back may arch, or the hip flexors will take over. The challenge is to maintain length through the spine and allow the legs to move freely without disturbing the rest of the body.

Leg Springs are wonderful for strengthening the hips and inner thighs, but they also teach coordination and control. The client has to manage the pull of the springs while keeping the centre engaged. At the same time, the arms are holding the poles overhead, which gives a gentle connection through the upper body and helps create length through the torso.

For teachers, it is also a very useful exercise to observe. Within a few repetitions you can often see how well someone controls their pelvis and how balanced their hip movement is. If the movement becomes too big or too fast, the control is usually the first thing to disappear.

I often remind clients that smaller, more controlled movements are far more valuable than large dramatic ones. When the exercise is done with precision, the springs create a beautiful feeling of support and resistance at the same time.

Leg Springs on the Cadillac are a perfect example of how Pilates works. The exercise may look simple from the outside, but it requires awareness, coordination, and control throughout the whole body.

And of course, after a few sets, most people realise that those polite-looking springs have been quietly working the legs far more than they expected. That is the magic of the apparatus.
