90/90 Hamstring

What it is

This movement enhances hamstring strength and flexibility from a bent-knee position. You lie on your back, extending one leg towards the ceiling from a 90-degree hip and knee bend. This effectively engages your hamstrings and calves through a controlled range of motion.

Technique tips

• Maintain a flat lower back throughout the movement.
• Gently support your bent thigh with your hands for stability.
• Extend your heel towards the ceiling, keeping the knee straight.
• Pause briefly at the top to enhance hamstring engagement.
• Control the return to the starting 90-degree position.
• Exhale as you extend your leg; inhale returning to start.

How to track your progress

Log the hold time of each set. Straddly keeps your best hold for this exercise and tells you when you beat it, so a two-second gain does not go unnoticed.
