My trainer Maree comes up with the best workouts. She never does the same routine twice which keeps things interesting and you always feel like you’ve worked really hard. The hill climb on this one nearly killed me.

If you’re not sure what some of these exercises are, I’ve found some demos on the net, just click on the links to watch.
