Fit Happens – Spring 2025

Spring 2025 Exercise Certainty in Uncertain Times To understand a scientific article, you need to appreciate the distinction between correlation and causation.

Winter 2025 Cardio Fitness for Body and Brain What’s a new year’s Winter Fit Happens without news about what’s happening in fitness news?

January 2025 Composite Score of 3 Heart Disease Biomarkers Excels High-sensitivity C-reactive protein (CRP), low-density lipoprotein (LDL, the bad cholesterol), and lipoprotein (a) levels (LPa) are valuable, and treatable, predictors of 5- and 10-year risk for cardiovascular events.

REAL News – November 2024

November 2024 Where Goes Muscle Mass With Cardio Exercise? Did you ever notice that cardio athletes tend to be lean but not mean?
