FAQ chi tiết

Conventional vs sumo — chọn cái nào?

Body biomechanics decide:

• Long arms + short torso → conventional
• Short arms + long torso → sumo
• Try both, pick comfortable + strong

Belt từ khi nào?

Khi squat / deadlift > 80% 1RM consistently. Trước đó: build natural core bracing first.

Deadlift daily được không?

Không. Heavy compound CNS-intensive. 1-2x/tuần max. Daily = burnout + injury.

Mua belt + chalk chính hãng?

• Belt: SBD official ($150), Pioneer Belt
• Chalk: Decathlon (~100k), Spider Chalk
• Strap: Versa Gripps, Pioneer ($30-60)
