As long as you have a stationary bike at home, access to one in a gym, or even a road bike with an indoor trainer, you can partake. The social media platform is chock-full of free, online cycling and Spin classes that vary in length, style, music choice, and difficulty, including options for beginners, HIIT enthusiasts, hip-hop fans, pro cyclists, and folks running short on time. That said, you don't need to attend a pricey studio class to score those benefits. (Not to mention, you get all the other general benefits of exercise.) Plus, indoor cycling has been found to improve aerobic capacity (the ability to use oxygen to fuel exercise activity), reduce blood pressure, and increase bone mineral density, research shows. Unlike running, this low-impact workout style won't leave your joints aching and, when synced with a killer playlist, can feel like a dance party - not a workout. But indoor cycling may be the most enjoyable way to hit your weekly quota. With all the sweating, huffing, and puffing involved, it's easy to hate on cardio.
