Leg training gets skipped more than almost any other body part among beginners, often simply because progress there is harder to see day to day than upper-body changes.
Leg muscles are among the largest in the body
Training this much muscle mass has an outsized effect on overall strength, hormone response, and calorie expenditure compared to smaller muscle groups.
Functional carryover is highest here
Leg strength directly supports everyday movement — stairs, carrying groceries, getting up from a chair — in a way that's easy to underrate until it's actually needed.
