If you can't touch your toes without struggling or bending your knees, you have limited mobility in your posterior chain muscles, which affects your ability to bend, hinge, and generate power efficiently.

WHATS LIKELY HAPPENING

Tight hamstrings + calves

Limited hip hinge control

Weak core support

What it leads to

Lower back strain

Poor lifting mechanics

Increased injury risk

What you can do

Improve flexibility, restore proper movement patterns, and build a stronger, more resilient posterior chain.
