Why does your face go red during exercise even though the sympathetic nervous system is activated which should divert your blood away from the skin and to your muscles instead?

The control of blood flow during exercise is more complicated than at first glance. At lower intensity exercise or at the start of exercise one of the main problems is heat. The blood carreis heat from the core to the skin allowing it to escape. During exercise heat would build up to dangerous levels is this system wasnt in place. However after more time the requirement of the muscles for oxygen outweighs the need to remove heat and so the blood flow to the skin is cut preserving more to flow to the the muscles.

How does the Sympathetic Division of the PNS regulate the body during exercise?
The SyNS pumps out epinephrine (adrenaline) during exercise to speed up heartrate, and regulate blood pressure. It also triggers the release of energy from your body's stores to fuel your muscles.
What in muscle cells increase as a result of exercise?
One thing that increases in our muscles when we exercise is lactic acid.
An exercise in which muscles are contracted and held for a few seconds but the body doesn't move?

What is the role of the sympathetic Nervous System on the gastrointestinal tract?
During sympathetic discharge, e.g., if you running away from a lion, gastrointestinal motility is suppressed and blood is diverted to muscles. At this point digestion is not a priority - at least not for the prey.
Why do some boys have six packs and some do not?

How do arteries supplying the leg muscles alter the rate of blood flow through them during exercise?
the sympathetic nervous system redirects blood flow from organs to the muscles and then the blood vessels of the organs constricts to prevent blood returning.

What muscle groups can you work out with exercise bands?

Is sympathetic active after you have eaten a meal?
Unless some other factor (e.g., a bear trying to attack you) activates your sympathetic nervous system, the parasympathetic, not the sympathetic, nervous system is active after eating. Parasympathetic activation results in a decline of the stress hormones epinephrine and norepinephrine, which allows blood to be directed towards the digestive system so that digestion and absorption of nutrients can occur. When the sympathetic nervous system is activated, blood is diverted from the "non-essential" organs, such as the digestive system, and towards the heart, brain, and muscles.
Why do muscles need more energy when you exercise?
