Can I skip leg day?
You can, but you probably should not if the goal is balanced strength, physique, performance, or long-term function. Legs are a large part of your body and support walking, stairs, sport, lifting, and independence.
Leg training does not have to mean a brutal session you dread. It can be scaled: squats, leg presses, split squats, hip hinges, hamstring curls, step-ups, sled work, or bodyweight progressions. The right version is the one you can train productively and recover from.
If you avoid leg training because of pain, fear, or past injury, get help choosing appropriate movements. If you avoid it only because it is difficult or unpleasant, reduce the drama and make it doable.
