Do lower body regularly train makes bigger upper body.?

 Let's start to learning why and how it happened.

Regularly training the lower body can indirectly contribute to the development of a bigger upper body through several mechanisms. These all are listed below.

1. Hormonal Response

Lower body exercises such as Squats, deadlift, sumo deadlift are compound movements that engage large muscle groups. These exercises stimulate that release of growth hormone and testosterone, which are key hormones involved in muscle growth throughout the body, including the upper body.

Main keys: compound exercises, large muscle groups, growth hormone & Testosterone.

2. Core Stabilization

Many lower body exercises, especially those that target the Posterior chain (e.g deadlifts), require significant core stabilization.
A strong and stable core provides a solid foundation for upper body movements, allowing you to generate more power and lift heavier weight during upper body exercises. 

Main keys: significant core stabilization, solid foundation, more power, lift heavier

3. Increased Strength, Power & Form

Build overall strength and power in the lower body muscles, which can improve performance during upper body exercises.

Greater lower body strength can support with maintaining proper form, generating force & handling heavier weights in upper body exercises: Bench press, Shoulder press, or some Rows.

Main keys: improve performance, proper form, generating force, heavier weights

4. Overall Muscular Symmetry

Developing a well-balanced physique involves training all major muscle groups, including both upper & lower body.

By regularly training the lower body, you promote overall muscular symmetry & proportions, creating a more aesthetically pleasing & well-rounded physique.

Main keys: muscular symmetry, muscular proportions, aesthetically pleasing, well-rounded physique.
