50 sit-ups
Please describe a starting heart rate and an ending heart rate!
A starting heart rate for doing 50 sit-ups will vary from person to person depending on their fitness level. On average, a resting heart rate for adults is around 60-100 beats per minute (bpm). However, as sit-ups involve physical exertion, the heart rate will increase during the exercise.
During the sit-ups, the heart rate will typically rise gradually as the body starts to work harder. Factors such as effort, intensity, and fitness level will influence the increase in heart rate. It's challenging to provide an exact range, as heart rate responses are highly individualized.
After completing the 50 sit-ups, the heart rate usually begins to reduce gradually as the body recovers. Again, the rate at which the heart rate decreases depends on several factors, including the individual's fitness level, recovery rate, and overall cardiovascular health. Generally, it may take a few minutes for the heart rate to return close to the resting level after exercise.
