Just because people you know are doing marathons or competing in HYROX doesn’t mean you have to force yourself to love running. If it’s not for you, it’s not for you. Not to mention there are plenty of other training methods that can improve your cardiovascular fitness, like with this four-move bodyweight circuit. It contains high reps, short rest periods, and compound exercises to help keep the heart rate high and cull calories. Just make sure you're wearing a good pair of workout shoes.
Despite this workout using bodyweight exercises, it can help boost muscle endurance, thanks to the high reps and completing the exercises one after the other with little rest. Healthline says muscle endurance is "the ability of your muscles to sustain repeated contractions against resistance over an extended period of time". According to the American Council of Exercise, this can "improve the aerobic capacity of working muscles" and the ability to carry out everyday activities without the muscles tiring.
