Which exercise method supports both physical fitness and daily commute?

Biking to work effectively supports both physical fitness and a daily commute because it combines transportation with exercise. Cycling not only contributes to cardiovascular health, strength, and endurance but also serves as a practical means of getting from one place to another. Incorporating biking into daily routines helps individuals maintain physical activity levels while commuting, allowing them to integrate fitness seamlessly into their schedules. This dual benefit makes it an efficient choice for those looking to enhance their fitness while also traveling to their destination.

The other options, while beneficial for fitness, do not inherently serve as methods of commuting. Gym workouts, group runs, and fitness classes are typically structured fitness activities that require a specific location and do not offer the practical aspect of transportation for everyday life.
