Five years ago, I earned my SFB (StrongFirst Bodyweight) Certification under StrongFirst Certified Master Instructor Karen Smith. The SFB StrongFirst Bodyweight Instructor Certification prepares you to teach bodyweight exercises safely and effectively, adhering to strict standards. To pass the strength test, women over 50 must perform a one-arm pushup (OAPU) from an elevation of 6-8 inches. Men over 50 and women under 50 must perform a one-arm pushup.
