Top 5 Alternatives to Running

1. Swimming. Swimming is a great place to start a cardio routine. It doesn't require you to support your own body weight (since the water is keeping you up) so it's a great option for those who are overweight. If you aren't a good swimmer, there are plenty of flotation devices you can use to help work your way up to a better swim.

2. Cycling. A bike is good low impact alternative to running. Unlike running, you can use a bike to actually get somewhere which can even save you gas money. Ride your bike to the gym or the store instead of your car or take a ride to your local park just for fun.

3. Walking on an Incline. If you like working out on the treadmill but can't run, try walking at an incline. Most treadmills go up to at least a 12% grade which can be just as challenging as a run.

4. Rowing. If you like doing your cardio at the gym but hate the treadmill, try using a rowing machine. These machines will get your legs and upper body in on the action to give you more of a full body workout.

5. Circuit Training. You can also try circuit training. Circuits use strength training exercises (free weights, body weight exercises, machines, resistance bands) with little or no rest in between sets. This keeps your heart rate up just like running and incorporates all the muscles in your body.
