Whats a good work out for the legs that i can do for 10 to 15 mins a day and doesn't require me to lay down

Man. You need to make every day leg day. Lol.

Cycling, or step ups which is even easier

I walk and go everywhere by bicycle, and have cyclist legs without any other effort. Rollerbladers get the most muscular legs but that's too much work.

Squats with weights.

As many reps of 1-min (or 90 sec) wall sits as possible

Squats, lots of squats and protein

Curls ups

they look like Stork legs and ya need more sunshine , Big Bird from sesame street , lol

They're a bit gangly. Run, do some squats, pack on some muscle and fat to those bones, my friend.
