A lot of people know that you should warm-up before you exercise, but forget and what else you should do.

The Mobilisation is the start of your warm-up, you would at least, mobilise the body-parts you are going to exercise.

Taking each muscle group through their range of motion, starting very gently controlled at first, once each area is mobilised and you’ve assessed that you have no problems with those areas, and so avoid injury in your proposed exercise session, you can start to warm each area up, and start integrating movements into a full warm-up.
