Legs
Quads: Standing on one foot pull the other foot up (while still pointing your knee down)
Hamstrings: band down at the waist to "touch your toes"
Calves: use a wall, put both hands on it and step away from the wall while keeping the leg that's being stretched straight. (one leg at a time)
Glutes (Butt): Sit down and pull one leg towards your chest while the foot is over the other leg.
Ankles: sit "japanese style" (not cross-legged "indian style") and lean back.

Trunk of body
Abdomen: lay down (face down) and push your body up with your arms while the rest is still laying down
Deltoids: (those are under , and slightly behind, your armpits) stand up, reach as high as you can with one hand and then lean to the opposite side of the body.
Back Muscles: while doing the Deltoids just lean forward at the waist
Arms
Shoulders: pull one straighted arm across your chest
Bicepts: from a standing position, arms at your sides, pull one arm straight back (without twisting it in any way left or right) (a wall or tall chair is useful too or a partner)
Tricepts: Reach for the sky and bend the arm at the elbow. Pull on it with the other hand (behind your head at the elbow)
Forearms: Pull your wrists inwards, then outwards (use the other hand to help stretch).
