Working out without an expensive gym doesn't mean you should be restricted in your choices. Indeed, you'll likely find yourself doing things you would never have done otherwise.
There's loads of great choices for cardio workouts. These are the main ones:
Walking or running: All you need for this is a good pair of shoes. Research shows that walking or running three times a week for at least twenty minutes is a great base for overall conditioning, with either a brisk walk or easy jogging effective in getting your heart rate going sufficiently.
Other methods of achieving a good home-based cardio workout include:
- Stair climbing
- Home versions of gym cardio machines - a stationary bike or stepper for example. These don't have to be expensive - there are always loads for sale in local newspapers, at garage sales, or on e-bay.
If you are buying equipment for home use, look for good quality equipment, and choose a machine that you enjoy using - too many homes have stationary bikes or treadmills that are used for nothing more demanding that hanging the ironing!
Alternatively you could put on your favourite music and dance, or use a keep fit video of some kind (aerobics, yoga, Pilates etc).
