Train Your Nervous System
At Formation, our method supports your physiology in powerful ways. You build cardiovascular endurance, coordination, rhythm, confidence, and muscular stamina every time you step into class. This article elaborates on another form of exercise you should consider adding to your workout routine.
For women in their 40s and beyond, adding heavy strength training alongside what you do at Formation will elevate your results. It supports bone, muscle, metabolism, and nervous system resilience in ways that become increasingly important with age. We want you to create a well-rounded plan for strength, longevity, and sustainable performance.
When you think about training, it is easy to focus on muscles, heart rate, or how hard a workout feels. Beneath all of that is the central nervous system, the brain and spinal cord that decide how efficiently you move, how much force you can produce, and how well you recover. For many women, progress stalls because their system is overstressed.
Strength Starts in the Brain
Early strength gains are driven primarily by neural adaptation, not muscle growth. Your brain becomes better at recruiting muscle fibers, coordinating movement, and producing force with less effort. This is why women often feel stronger before they see visible changes. It is also why chasing exhaustion does not equal better results. Excessive fatigue can blunt the very neural signals that drive adaptation.
Stress, Cortisol, and “Why Does This Feel So Hard?”
The nervous system also plays a central role in stress regulation. High-volume or poorly fueled training increases cortisol and keeps the body in a constant state of alert. Many women recognize this feeling as disrupted sleep, low motivation, or workouts that suddenly feel harder than they should. Training with recovery, rest intervals, and appropriate intensity teaches the nervous system to handle stress and return to baseline more efficiently.
40s, 50s, and Beyond
This becomes even more important with age and during perimenopause. As estrogen fluctuates, tolerance for fatigue drops, but responsiveness to clear, heavy, well-rested strength work remains high. Fewer reps, higher-quality effort, and adequate recovery protect neural health while preserving strength, coordination, and confidence in movement.
What This Looks Like in Practice
Lift heavy, keeping reps lower
Rest 2 to 3 minutes between heavy sets
Stop just shy of failure most days
Sleep 7 to 8 hours
Eat enough protein and total calories
Make a well-rounded workout plan that includes movement that challenges your heart, brain, and strength. When the brain and body communicate well, strength improves, stress decreases, and long-term health becomes easier to sustain.
