Stiff legged deadlifts -
First of all, do you know normal deadlifts??? If you've ever done a Body Pump class, stiff legged deadlifts are the ones they do in there!
Feet shoulder width apart, knees very slightly bent (pretty much straight but not locked out), hands hold the bar in an overhand grip resting just outside the thighs.
The movement is to take it from where the hands hang to the knees and back up, making sure your shoulders are back and your eyes are staring about a metre in front.

You got me on that one
Donkey Calf Raises -
I'm assuming these are just like regular calf raises?! You probably already know this one but...
You can use a step or the edge of a stair or something, just put your foot on it enough that you won't slip off and raise up onto your toes and then drop your heels as far down as you can.
