Interval training, the perfect ally for endurance
The aim here is to tone muscles without straining them violently.
You'll take a short break after each exercise corresponding to the amount of time it takes to carry out the exercise. For example, you'll take a 30-second break after each 30-second exercise. The session should not exceed 15 minutes (including breaks),
I recommend focusing on exercises such as squats, planks, squat jumps, squats with legs spread/close together, side planks, pumps, and ab exercises. Choose the muscles you want to tone and select the corresponding exercise.
The main thing is to stick to the 30-second exercise/30-second break formula to work on your endurance and also burn calories.
I'd just like to point out that the ideal is to start with running and combine it with the session I'm about to present.
