Core Concepts and Philosophies

Dr. Sims emphasizes the importance of understanding the intricate interplay of hormones and hormone cycles in women's bodies. This knowledge is crucial for designing personalized nutrition and training programs that optimize outcomes. She highlights that women are metabolically more flexible than men due to having more oxidative fibers in their muscles, making them less responsive to fasting and fasted workouts. Dr. Sims challenges traditional fitness approaches, urging women to prioritize fueling appropriately for their training, particularly during periods of hormonal fluctuation. She advocates for aligning nutrition and exercise with the circadian rhythm, recognizing the impact of cortisol fluctuations throughout the day. She also stresses the significance of individualized approaches, emphasizing that the best plan is the one that caters to your specific needs, goals, and stage of life.

Practical Strategies and Advice

• Fuel Up for Training: Prioritize pre-workout nutrition, even if you're not hungry, to reduce stress, regulate cortisol, and enhance performance. For a strength training session, aim for 15 grams of protein. For cardio workouts under an hour, add 30 grams of carbs to that.
• Prioritize Protein: Women need more protein than men, especially after exercise. In your reproductive years, aim for 35 grams of high-quality protein within 45 minutes of your workout. This increases to 40-60 grams for perimenopausal and postmenopausal women.
• Embrace Resistance Training: Resistance training is crucial for women at all ages, but particularly important for those over 40. It supports strength, muscle mass, and bone mineral density, contributing to a healthy lifespan. For women 30 and younger, train to failure to maximize strength and hypertrophy. For women 40 and over, prioritize strength with two to three reps in reserve.
• Polarize Your Training: Incorporate both high-intensity and low-intensity activities for optimal health and longevity. This means incorporating true high-intensity interval training (HIIT) sessions, such as 1-4 minutes of hard work at 80% or more intensity, with adequate recovery. Supplement this with lower-intensity activities like walking for recovery and rest.
• Track Your Cycle: Women should track their menstrual cycles to identify individual patterns and adjust their training and nutrition accordingly. The low hormone phase is optimal for pushing high-intensity workouts, while the luteal phase requires extra attention to nutrition and rest.
• Listen to Your Body: Pay attention to your body's signals and adjust your training intensity accordingly. If you wake up feeling sluggish, give yourself a 10-minute grace period to see if your energy levels improve. Don't be afraid to reduce intensity or take a rest day if needed.
• Consider Supplements: Supplementation can be a valuable tool for women's health, particularly creatine and vitamin D3. Creatine has been shown to benefit brain health, mood, and gut health. Vitamin D3 is crucial for iron absorption, bone health, and overall well-being.
• Prioritize Sleep: Adequate sleep is essential for women, particularly during the luteal phase and perimenopause. Practice good sleep hygiene, consider supplements like L-theanine and valerian root, and explore non-sleep deep rest techniques like Yoga Nidra.
• Embrace Heat Exposure: Sauna use, especially Finnish saunas, offers numerous benefits for women, including improved insulin sensitivity, heat shock protein expression, and serotonin production. It can help manage hot flashes and night sweats associated with menopause.

Supporting Evidence

Dr. Sims bases her recommendations on extensive research, including her own groundbreaking studies. She cites research that emphasizes the importance of protein and carbohydrate consumption after exercise for women, the unique effects of high-intensity training on hormone profiles, and the positive impact of both resistance training and HIIT for women across the lifespan. She also highlights studies that have explored the benefits of heat exposure, especially sauna use, for women, specifically emphasizing its potential for managing menopause symptoms.

Personal Application

Dr. Sims shares her own experiences, detailing her personal preferences for coffee with Ashwagandha and a morning protein shake. She acknowledges the importance of adjusting her training based on her stage of life and personal preferences, highlighting that she prioritizes activities she finds enjoyable and empowering. This provides a relatable and authentic perspective, demonstrating that even experts embrace a balanced approach to health and fitness.

Recommendations for Tools and Techniques

• Cycle Tracking Apps: Use cycle tracking apps to monitor your menstrual cycle, identify individual patterns, and adjust your training and nutrition accordingly. Popular options include Clue, Flo, and Ovia.
• Bodyweight Exercises: Explore bodyweight exercises for a convenient and accessible way to build strength and muscle. This could include squats, lunges, push-ups, and planks.
• Home-Based Resistance Training: Use readily available tools like resistance bands, kettlebells, or dumbbells to create a resistance training routine at home.
• Online Fitness Resources: Utilize online resources like YouTube channels and websites dedicated to women's fitness to learn proper form and technique for various exercises. Popular options include Haley Adams, Brie, and Sunny Webster.
• Sauna: Incorporate sauna use into your routine, aiming for sessions of 15-30 minutes at temperatures between 185-210 degrees Fahrenheit.
