📚 What the Science Says
✅ Safe & Effective for Midlife and Beyond
A study by Millar et al. (2014) in the Journal of Clinical Hypertension found that isometric resistance training significantly reduces systolic blood pressure in adults over 45 — a critical factor in stroke and heart disease prevention.

🧬 Neuroplasticity Benefits
Research in Neuroscience Letters (Chang et al., 2018) shows that regular isometric contractions increase brain-derived neurotrophic factor (BDNF)—a key molecule in neuroplasticity, mood regulation, and memory retention.

💪 Efficiency Without Risk
Isometric training has been shown to provide substantial strength gains with minimal joint stress, making it ideal for aging populations with arthritis or limited mobility (Hunter et al., 2016).
