THE MOST RESEARCHED BODY IN MARKETING
THE LEAST IN MEDICINE
“A woman is not a small man,” said Stacey Sims. Female bodies perform, process, and recover differently, yet for decades, women were largely excluded from medical research, leaving female physiology misunderstood in both sport and modern fitness. Understanding how women train, recover, and fuel their bodies is essential to improving performance, confidence, and long-term health.
A key factor in women’s fitness and athletic performance is the menstrual cycle. Hormonal shifts throughout the month directly impact energy levels, strength, endurance, and recovery. By tracking your cycle and aligning your workouts with these changes, women can optimize training, support hormone balance, and avoid burnout. This approach, often referred to as cycle syncing or biohacking for women, allows for more efficient and sustainable results.
The menstrual cycle is divided into two main phases: the follicular phase and the luteal phase. During the follicular phase, higher estrogen levels support increased energy, strength, and faster recovery, making it the ideal time for high-intensity workouts, strength training, and endurance-based exercise. In contrast, the luteal phase is driven by rising progesterone, which can lead to fatigue, increased body temperature, and decreased coordination. During this phase, lower-intensity workouts like Pilates, walking, and light strength training are more effective, helping women work with their bodies instead of against them.
Training in alignment with your cycle not only improves physical performance but also supports mental well-being and hormonal health. Overtraining, especially during the luteal phase, can disrupt hormones and increase fatigue, making it even more important to listen to your body. As highlighted in Sims’ research, women’s performance can fluctuate depending on their cycle, unlike men, whose hormonal patterns remain more consistent.
JIV Athletics was created with this understanding at its core, supporting women’s fitness, performance, and confidence through a science-backed approach to movement. From high-performance underwear to supportive bodysuits, JIV Athletics designs garments that move with the female body through every phase of the cycle. By combining education on women’s health, cycle-based training, and elevated athletic essentials, JIV empowers women to train smarter, feel stronger, and perform at their best, every day of the month.
