A Sunday morning rucksack march after a quick warm up of pushups and sit-ups. Stretch well both before and after the ruck march. Remember to drink plenty of water and stay hydrated out there. The weather is warming up and it is very important. And the other thing is again, to ensure that you have at least two pairs of boots broken in for the course.

2 x 20 Pushups
