The main muscle groups you will most likely target during a workout routine within a variety of sports are listed below:

Leg Muscles

Quadriceps – This group of muscles makes up the front and sides of the thigh. This muscles wraps around the bone and is divided up into four major muscles. These four quadriceps muscles are extensors of the knee joint, and are very powerful. This muscle is involved in everyday activities such as walking, and also running, jumping, and of the sort.

Exercises that may be performed to strengthen quadriceps include squats, lunges, leg extension machine, and leg press machine.

Hamstrings – These muscles make up the back of the thigh. The hamstrings act upon two joints, the hip and the knee. Again hamstrings are part of daily walking, and also running, jumping and other activities that require much motion.

Exercises include squats, lunges, leg press machine, and leg curl machine

Calves – The calf muscles are on the back and lower leg. They include the gastrocnemius and the soleus. The gastrocnemius is what gives the calf its strong rounded shape. The soleus is a flat muscle running under the gastrocnemius. Calves are also used in daily routines such as walking, running, and so on.

EXERCISES: Standing calf raises give the gastrocnemius a good workout, while seated or bent knee calf raises place special emphasis on the soleus. These small muscles can handle a relatively large amount of weight.

Abs

Abdominals – These muscles include the rectus abdominus, a large flat muscle running the length of the abdomen, and the external obliques, which run down the sides and front of the abdomen.

Exercises: standard crunches, curls, reverse curls/crunches, and crunches involving a rotation or twist (to stimulate the external obliques)

Chest

Pectoralis major – Large fan shaped muscle that covers the front of the upper chest. This muscle is the largest muscle in the chest.

Pectoralis minor – Thin, triangular muscle, situated at the upper part of the chest, beneath the Pectoralis major. It is the smallest muscle in the chest and plays a role in shoulder movement.

Chest exercises: push-ups, chin-ups, regular/incline/decline bench press, fly machines/dumbbell flies, and dips.
