حاسبة معدل ضربات القلب المستهدف – مناطق التدريب

💡 هل تعلم؟

• The American College of Sports Medicine recommends training at 64–95% of maximum heart rate to achieve meaningful cardiovascular improvements.
• Heart Rate Variability (HRV) — the tiny variation in time between heartbeats — is used by elite athletes and coaches as the primary daily indicator of recovery status.
• The "fat-burning zone" (50–70% max HR) burns a higher percentage of calories from fat, but higher-intensity training burns more total calories per minute — and more total fat calories over the day.
