The Hundred on the Pilates Reformer is basically the same as the Hundred on the Mat but with straps and resistance from Springs. While on the Mat, the Hundred is the first exercise in the order. On the Reformer, the Hundred usually comes after Footwork. Since the Footwork, Hundred and the next couple of exercises are all designed to warm you up and prepare your body for what is to come it is often done on 3 or 4 springs. But this can be adjusted if necessary. The Hundred on the Reformer will reveal what the Hundred on the Mat often cannot.
The 100 is meant to warm you up. Get your whole body involved!
After you complete your Footwork, lower your footbar. Ideally, you can do this without sitting up. But if you must sit up, try to keep your body connected to all that you turned on. For example, you can "teaser up" and hold your Teaser while you lower your footbar and adjust your springs if necessary. Lay back down and grab your handles. Reach your arms up to the sky and if possible place your legs straight out resting on Reformer. If straight legs on the Reformer is too difficult, you can start with them bent into your chest. Then in one movement press your arms straight down, lift your head, chest, and legs up (or out) to a high diagonal and begin to pump your arms as you breathe in and out for 10 cycles. To finish, reverse how you got into position.
As you are pumping your arms notice what is moving. Hopefully, just your arms are moving. If you notice your head and chest are bouncing or that the carriage is inching back and forth, this means we need to connect you more to your center. Feel the handles press back into your hands equal to how much you are pushing into them. This should mitigate the bouncing of the carriage. Hug your legs tight together and don't be afraid to feel your seat engage here to support your legs. Remember this is an exercise to warm you up, so get your whole body involved!
