Can't touch my toes without bending my knees while standing.

Same here. I've always wondered too. I can't do it when sitting either. 5'11" and 170lbs. Not fat. Fairly skinny.

Ditto, I'm 6'3 avg. build and cant do it but my sister is 5'11 and can palm the ground without bending her knees.

It's probably hamstrings. Hamstrings are one of the most common points of poor flexibility, due to our sedentary lifestyles with our legs always bent.

Just do stretches 10 minutes a day and you'll see improvements.

probably hamstrings. you should watch this though before you just start stretching them.

look up pnf stretching and do this stretchs every other day. after warming up your ankles.

you will be able to touch your toes in 2 weeks at most. touch the ground in 3-4 weeks and thumb on the floor in 2 months.(probably faster)

I have the same problem. I've been stretching every day for 2 weeks now. No progress at all. Any idea what's going on?

270lbs/6'3 fat ass who sat in front of the computer or slept 90% of his life here and I can easily palm the ground
Easy good grades at PE lessons, even tho I sucked at everything else

do pnf stretching

Just do romanian deadlifts. Each rep is a weighted stretch on your hamstrings.
I do them standing on a plate now because I'm flexible enough that I can hit the floor with regular 20kg plates on the bar.
