Unlock the Power of Your Period With This New Program on Tonal

Cycle Sync Strength features workouts that line up with the different phases of your menstrual cycle to optimize your training.

Tonal coaches Ash Wilking, Tanysha Renee, Kristina Centenari, and Kendall Wood.

Turn Your Cycle into a Superpower

Shifting levels of estrogen and progesterone during the menstrual cycle affect muscle protein synthesis, energy levels, strength development, and other factors that influence athletic performance. That’s why the new four-week program, Cycle Sync Strength, was designed specifically for athletes with periods and includes cycle-syncing workouts that complement the hormonal phases of your menstrual cycle for optimal training.

Launching on Tonal Monday, April 3, each workout is led by one of four female coaches, Ash Wilking, Kendall Wood, Tanysha Renee, and Kristina Centenari, and focuses on playing up your strengths during that particular week.

Taking advantage of these hormonal shifts by aligning your workouts with your cycle will help you break through plateaus and crush your goals. 

Science-Based, Expert-Backed Workouts to Get Stronger Faster

Cycle Sync Strength was created in collaboration with female physiology expert Stacy Sims, PhD. Sims is a leading global expert on exercise nutrition and performance for women, and the author of Roar: How to Match Your Food and Fitness To Your Female Physiology For Optimum Performance, Great Health, and a Strong, Lean Body For Life. She’s a senior research associate at Auckland University of Technology, has directed research programs at Stanford and the University of Waikato, and has published over 70 peer-reviewed papers on athletic performance.

An advocate for training with your physiology, not against it, Sims helped design these workouts so you can lift heavy and push for PRs when your body’s most resilient against stress, then focus on recovery and mobility on days when you’re more fatigued. It’s a smarter way to train that’ll help you perform at your best every day of the month.
