4. ADD HIIT WHEN YOUR FITNESS LEVEL ALLOWS IT.
HIIT combines short periods of hard effort with recovery periods.
Try:
• 30 seconds of hard effort
• 90 seconds of easy recovery
• Repeat for several rounds
HIIT improves cardiovascular fitness and increases energy expenditure.
Build your fitness first.
Then introduce high-intensity work gradually.
Lower-impact movement remains a strong starting point for people with limited experience, significant excess weight, or joint problems.
