I do a lot of running and cycling but doing only these activities means that you might not gain an overall level of all-round fitness. Try Interval and Calisthenics training for a more all-round workout.
Originally called Fartlek (a Swedish term meaning “speed play”), interval training combines alternating short and fast bursts of intense exercise with slower, easier activity. Fartlek training was a deliberate attempt to complete more work than continuous training by increasing the intensity of workouts. Definition from https://stretchcoach.com/articles/interval-training/.
Calisthenics or callisthenics is a form of strength training consisting of a variety of movements that exercise large muscle groups, such as standing, grasping, pushing, etc. These exercises are often performed rhythmically and with minimal equipment, as bodyweight exercises.
