Because you can do more flowing motions with them, the weights also increase your aerobic fitness and flexibility. You can use one for a solo workout or use two if you are training with a partner, and they're suitable for kids and grown-ups.
An Italian word for strength and power, forza is a class-based in Japanese sword-fighting techniques. A wooden sword is used as a stand-in for metal as participants slice, chop and thrust it through the air in addition to doing lunge movements or taking steps with their legs.
Forza offers a fun way to discover one's inner samurai: It's a demanding physical workout that shapes both the arms and legs; at the same time it's mentally rigorous and requires plenty of concentration. Forza gives new meaning to the phrase "workout warrior."
If you haven't been on a trampoline since childhood, urban rebounding might make you feel like a kid again. The class is taught on a mini-trampoline, used for much of the session.
The trampoline provides an unstable surface to jump on that makes the exercise more challenging; it also cushions the landing and places less stress on your joints than a floor-based workout.
Urban rebounding requires some coordination, because your arms and legs will often be moving simultaneously, and you'll get a high-energy, heart-thumping, whole-body workout in the process.
The activity not only improves your balance but also builds aerobic conditioning as well as arm, leg and core strength.
The novel twist in this class is that it is taught on a Bosu ball, a piece of exercise equipment shaped like a half-dome. Bosu is an acronym that stands for "both sides utilized" because you can face the blue rubber shaped dome up and exercise on top of its surface or flip it over and work with the base of the device.
Many of the moves are similar to those in a step aerobics class, but the main difference is that the Bosu offers a wobblier surface than the step. You can stand on the Bosu, lie down or place your knee on it or use your arms to push off of it.
Any exercise you would do on the ground, whether it's lunges, squats, crunches or pushups, becomes trickier when attempted on a Bosu ball. Participants develop balance, and it tones muscles as the class works the upper and lower body as well as the midsection. Bosu training also has cardio elements to it.
