The majority of your training efforts should focus on large compound movements. Squats, Lunges, Twists, Bend Patterns (deadlifts), Pushes, and Pulls.
Not only are these movements essential to everyday living and sport, but they provide the most positive training effect. Isolating single muscle groups is beneficial in rehab circumstances, or in the world of bodybuilding. Focus your efforts on the larger compound movement in order to utilize more muscles per movement, increase the rate of caloric expenditure, and train your body to move more efficiently.
Not only is this style of training more beneficial in terms of body composition change and fat-burning, but it’s helping you move more efficiently in life.
