Exercise is an activity requiring physical effort, carried out to sustain or improve health and fitness. In the past, people used to focus only on improving their performance and carrying out aerobic exercises, whereas nowadays, they focus more on overall health and also long-term sustainability and recovery. Exercise is important for us because without physical activity, our bodies get weaker, and organs deteriorate. Therefore, it allows people to stay healthy and keep not only their bodies in form but also their minds healthy. Exercise-related supplements have become very popular and in this work, we research some supplements and their effect on exercise at a biochemical level, in addition to single molecules and metals that aid in exercise optimization. We learned that protein from different sources have varying effects and even vary in how readily the body absorbs them. Small molecules such as the amino acid leucine and even metals like magnesium can change the recovery profile after exercise. We also studied the relationship between exercise and some biomarkers. Taken together, we show that optimizing exercise for best results and fastest recovery is a complicated task that involves diet, type of exercise, sleeping patterns, and other factors. Future work could focus on one of these factors and continue to demystify the best ways to exercise.
