Make Your Own Breeze If you're committed to your indoor cycling classes, here's your chance to put your bike fitness to the test. All the benefits of cycling — cardio, muscle strengthening, and low-impact movements — translate from inside to outside. Plus, there's nothing like speeding along an open road or rocketing down a trail to create a little natural air-conditioning. Aim for the early morning or early evening to avoid the most intense rays of the day. Image Source: Shutterstock
