Over four weeks, the "sedentary but healthy" participants were put through a training program that used bodyweight exercises like squats and press-ups to build full-body strength.
They did these exercises for just five minutes, but did them every day. In four weeks, all participants showed a "significant" improvement in muscle strength, endurance, and flexibility, along with a drop in heart rate after exercise. While the drop was small, it shows the group recovered quicker after the program, pointing to improved heart health.
