Based on studies from 2015 to 2024 by researchers like Llion A. Roberts from the University of Queensland and Emma S. Malta from Victoria University, cold water immersion was tested after workouts. Trials involved people doing strength training, then plunging in cold water or doing active recovery, measuring muscle gains, soreness, and performance over weeks.

This statement by Dr. Gabrielle Lyon isn’t just catchy—it’s scientifically sound. A 2024 Scientific Reports study analyzing nearly 11,000 adults found that a high lean mass to visceral fat ratio was tied to up to 88% lower risk of type 2 diabetes and significantly fewer cases of high blood pressure and abnormal cholesterol levels.

A 2021 review in Nutrients by Smith‑Ryan et al. highlights that women have 70–80% lower natural creatine stores than men, making supplementation especially impactful for their health and performance.

A systematic review and meta-analysis from the University of New South Wales (2021) examined 58 studies with 3,000 beginner participants and found that pure strength training alone led to around 1.4% total body fat loss—almost identical to what you’d see from cardio.

In 2025, Cannavaro, Leva, Caturano, Berra, Bonfrate & Conte (Université Clermont Auvergne & CNRS) reviewed research on using amino acid supplements during weight loss. Their Nutrients paper finds that certain amino acids—especially leucine, HMB, and collagen peptides—help protect lean mass when you’re slimming down.

In 2025, Dr. Richard Kreider of Texas A&M reviewed 685 clinical trials and found creatine to be not only safe, but vital for healthy aging. Beyond muscle gains, creatine powers brain cells, supports cognitive function, protects against stress, and helps older adults retain muscle and memory.

A 2022 meta-analysis in the Journal of Science in Sport and Exercise reviewed 16 animal studies and found that stretching for at least 15 minutes daily led to significant increases in muscle mass, cross-sectional area, fiber size, and even fiber number.

A 2025 double-blind, placebo-controlled trial found that creatine monohydrate supplementation reduced post-exercise muscle damage and soreness, especially in women, who experienced less swelling. This suggests creatine can help maintain muscle function and comfort after intense training.
