Benefits vs Risks

Disadvantages of HIIT Training

While effective, HIIT isnt riskfree. Common pitfalls include:

• Joint stress from highimpact moves (burpees, box jumps).
• Excess cortisol if you train >3times/week without adequate rest.
• Potential for burnout if intensity is always maxed out.

How Redditors mitigate those risks

Most seasoned posters emphasize:

• Starting with lowimpact variations (stepback lunges instead of jumps).
• Scheduling at least one activerecovery day.
• Listening to your bodyif soreness lingers >48hours, dial back the volume.

For medical clearance, a quick check with your primarycare physician (Mayo Clinic recommends it for beginners with preexisting conditions) can add an extra layer of safety.
