Inchworm

What it is

This dynamic bodyweight exercise involves walking your hands out to a plank position, then walking your feet to meet your hands. You'll primarily target your hamstrings for improved flexibility. It also effectively engages your core for stability and full-body control.

Technique tips

• Keep your legs straight to maximize the hamstring stretch.
• Initiate the movement by bending only at your hips.
• Maintain a strong, stable core in the plank position.
• Walk your hands forward slowly and with control.
• Take small, deliberate steps with your feet.

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.
