FAQ chi tiết

Squat depth — phải parallel + không?

Ideally below parallel. Knee crease below hip = parallel+ depth.

Anatomy varies:

• Mobility-restricted: above parallel OK temporarily
• Work to improve depth gradually
• Don't sacrifice form for depth

Bao lâu thấy leg grow?

• Newbie: 4-8 weeks visible
• Intermediate: 3-6 months gradual
• Genetics determine ceiling
• Year 1: noticeable; Year 2+: significant

Squat hỏng đầu gối phải không?

Myth busted. Proper squat:

• Builds knee strength
• Improves joint health
• Strengthens surrounding muscles

Bad form damages knees, not squat itself.
