Why Cycle-Sync Your Workouts?

Your hormones influence everything from strength and stamina to coordination, endurance, and recovery. That’s why some days you’re ready to smash a HIIT class, and others, even a walk feels like a stretch.

Syncing your workouts to your cycle isn’t about doing less—it’s about training smarter. You’ll feel more energised, less burnt out, and more in tune with what your body actually needs.

The Four Phases of Fitness

Menstrual Phase (Days 1–5)

Hormones are at their lowest. You may feel tired, crampy, or emotionally flat.

Ideal movement:

Rest, walking, gentle stretching
Yoga nidra, light mobility work
Or simply nothing at all—and that’s valid too

This is a time to recover, not push. Honour the slowdown.

Follicular Phase (Days 6–14)

Estrogen begins to rise, bringing more energy, mental clarity, and motivation.

Ideal movement:

Strength training, creative movement, dance
Cardio that’s energising but not too intense
Trying something new: a new class, route, or routine

You’ll likely feel ready to challenge yourself—go for it.

Ovulatory Phase (Around Day 14)

Estrogen peaks. You’re at your strongest, most coordinated, and most sociable.

Ideal movement:

High-intensity workouts, group classes, running
Heavier lifts, interval training, boxing or spin
Partner workouts or dance-based sessions

This is your performance phase. Make the most of it—but always check in with how you feel first.

Luteal Phase (Days 15–28)

Progesterone rises, and your energy may start to dip. You may feel less inclined to go all-out.

Ideal movement:

Low-impact strength training, Pilates, barre
Walking, stretching, yin yoga
Adjust intensity as you move through the phase—early luteal can handle more than the final days

This phase is all about steady, grounding movement—not pushing through just because it’s on the plan.

Listening to Your Body Is the Goal

There’s no one-size-fits-all. Some cycles you might feel great in ovulation, others you’ll want to nap through luteal. The goal isn’t to follow a rigid workout schedule, but to check in and choose what feels right today.
