Carbohydrates are your body's main energy source, fats are energy too but the energy in carbohydrates (including sugars) is easier to break down.
Fatty Acids
The primary disadvantage of using fat as fuel during endurance exercise is that it is not entirely clear where the fat used comes from. It is not certain whether it is adipose tissue, which the body has plenty of, or intramuscular triglycerides that are stored in muscle fibers.
The primary muscles used during a squat exercise are the quadriceps, hamstrings, glutes, and lower back muscles.
The primary muscles activated during a front lever exercise are the latissimus dorsi, core muscles, and the muscles in the arms and shoulders.
The primary fuel source for muscles during exercise is glucose, which is derived from carbohydrates in the diet. Once stored glucose is depleted, the body can also use stored fat for energy through a process called lipolysis. Additionally, during prolonged exercise, muscles can rely on protein breakdown for energy.
The primary substrate used to provide energy at rest during high intensity exercise is muscle glycogen. As exercise intensity increases, the body relies more heavily on glycogen stored in the muscle to fuel the activity due to its quick conversion into energy.
The primary muscle groups targeted during a lat pulldown exercise are the latissimus dorsi (lats), biceps, and muscles in the upper back and shoulders.
The primary muscles targeted during a lat raise exercise are the deltoid muscles in the shoulders.

The primary muscle groups targeted during a chest press exercise are the pectoral muscles (chest muscles), the deltoids (shoulder muscles), and the triceps (back of the upper arm muscles).
