This is a response to increased work by the muscles and an escalating need for oxygen throughout the body. Once you have finished exercising, your breathing and heart rate slowly return to normal, and the more exercise you perform, the more efficient this system becomes.our heart rate will still increase while exercising, but not as sharply because the heart is strengthened; your breathing will intensify, but you may be less winded.
