fencing workout tips

Next week  I'm going to a fencing camp :D So I'm trying to get a bit into shape cause I haven't fenced in nearly 2months. I'm sure the 16 year-olds are going to tire me out prancing up and down the piste but I'm going to try! I've been doing some rope skipping, lunges and stretches but I have been too lazy to go jogging etc. Today on the beach I ran in the water and tried a few basic exercises as shown on the following video, I found it very effective due to the resistance but also thanx to the waves.
