After a tiring day, it is difficult for people to ignite the passion for exercise. According to a recent report on the US "MSN" website, senior personal trainer Renita Brannan recommended 8 sets of exercises so that you can strengthen your body and burn fat easily without leaving your desk.

1. Sitting and doing abdominal crunches (Figure 1). Sit up straight, lift your back away from the back of the chair, and straighten your spine upwards; then take 10 deep breaths, and draw your abdomen back as much as possible every time you exhale, as if you are doing an abdominal crunch. This movement stretches the spine and exercises the core muscles. ExpectedCalories burned: 15 calories.

2. Chair squat (Figure 2). Sit on the edge of the chair, place your arms in front of you or stretch above your head; then stand up straight, inhale slowly, sink your body, and gently sit back on the edge of the chair, repeat 10 times. You can also increase the difficulty: bend your knees and hang your buttocks over the chair for 30 seconds. At this time, you will feel the heat in your buttocks and thighs burning. Estimated calories burned: 20 calories.
