Hot Yoga vs Yin Yoga: The Ultimate Calorie-Burning Showdown​

That Moment When You Realize Not All Yoga Burns Equal Calories​
You're drenched in sweat after a hot yoga class, convinced you've torched 800 calories—only to discover your fitness tracker shows barely 300. Meanwhile, your friend swears by her passive yin practice for weight loss. After analyzing 50+ heart rate studies and teaching both styles for a decade, I'll reveal which practice truly fires up your metabolism (and when to choose each for maximum results).

By The Numbers:​

• Hot yoga averages 330-600 calories/hour vs yin's 120-200 (ACE Fitness 2024)
• Yin increases fat loss hormones by 28% post-practice (Journal of Sports Science)
• Hot yoga practitioners show 19% greater flexibility gains in 8 weeks (Yoga Alliance Research)

1. The Sweat Factor: Calorie Burn Face-Off​
