Extreme weather doesn’t have to put an end to your fitness routine, even if the treadmill or stair-stepper seems boring compared with jogging or riding your bike outside. What’s important is to ask yourself: How can I make exercise different to make it more motivating? If you’re seeking an answer, you may want to consider these five indoor fitness options, the American Council on Exercise (ACE) says. Some build on familiar activities, but others may be new to you. Always keep some variety in your exercise routines, to prevent boredom and drop out. If you haven’t been exercising regularly, be sure to check with your health care provider before beginning a new exercise routine.
