Maximize Midlife Fitness: HIIT & REHIT Empowering Women in Menopause
Why HIIT (and REHIT) Are a Midlife Woman’s Best Friend Let’s be honest — midlife doesn’t play nice. Hormones shift, metabolism tanks, and your old workouts stop working. That’s where High-Intensity Interval Training (HIIT) becomes a game-changer for perimenopausal and menopausal women.
Why HIIT Works So Well in Midlife:
-
Boosts metabolism and helps burn stubborn belly fat.
-
Improves heart health — crucial post-menopause.
-
Builds muscle and strengthens bones (goodbye, osteopenia).
-
Regulates stress hormones and lifts mood.
-
Saves time — just 20–30 minutes for real results.
Enter REHIT: The Smarter, Faster HIIT
REHIT (Reduced Exertion HIIT) is like HIIT’s time-hacking cousin — just as effective, sometimes more, in only 5 minutes. It’s science-backed, beginner-friendly, and ridiculously efficient. Perfect if you’re low on time, energy, or motivation.
How it works:
-
2 all-out sprints, 20 seconds each
-
A bit of warm-up and cool-down
-
Done in under 5 minutes, 2–3x a week
