💪 Slow & Hard Upper Body Flex

Today I’m sharing 10 minutes of slow and controlled upper body flexing, filmed on June 10, 2026.

You’ll see front, side and back poses as I tighten my biceps, shoulders and back muscles with steady control and deliberate contractions. Every pose is held to show the muscle shape from different angles.

The bonus features additional hard biceps poses from the front and back, plus close-up moments where I press and feel my flexed biceps to show how solid they are.
