It is recommended that you train these muscles simultaneously.

Gym-goers' worst fitness error is exercising all muscle groups. The idea is to combine aerobic and weight training to gain muscle rapidly. Unfortunately, an hour-long workout cannot address all muscle groups. 

Focusing on a few different muscle groups at a time can help you notice more progress. If you want to build your core quickly and efficiently, the key is to use the correct muscle groups at the same time.

Working all your muscles is fine. When time is tight, target certain muscle groups. This method helps novices shed weight and gain power. This prepares for advanced training.

Muscles in the back and abdomen make up what is called the core muscles. You may thank this cluster of muscles for maintaining your posture and equilibrium. These are the primary muscle groups that participate in every type of physical activity. 

If you want better posture and less back discomfort, strengthen your core muscles. To strengthen your abdominal muscles, try exercises like the pelvic tilt, plank, and crunches. The core muscles are the main target of these workouts.

The muscles in your chest, shoulders, and arms form a push, because they coordinate to force the obstacle away from you. You may strengthen your upper body's main muscles by focusing on these three areas simultaneously. 

It is true that gaining muscle in the upper part of the body might give the impression that a person is overly muscular. Bench presses, push-ups, and overhead presses are all exercises that may be used to target this particular group of muscles.

These two muscles pull resistance toward the body, making them pull muscles. Targeting these muscles together is straightforward because they are linked. Use pull-ups and deadlifts to target these muscles. Bicep curls are another good option.

It is easy to attack these muscles simultaneously. Multiple workouts exist that specifically target the muscles in both the arms and the legs. You can work these muscles simultaneously by doing things like bicep curls with standing forward lunges, push-ups, and rowing workouts in the gym.

After working out these muscle groups on various days, you can take a rest for one or two days to allow your muscles to recover. In order to facilitate muscle recovery, it is beneficial to take breaks in between your training routine.
