For those of you who fancy getting a little fitter or those who are already members of a gym but want to try something different, British Military Fitness offer a free trial lesson at one of there many outdoor sites across the UK.
Go onto the website and look in the classes section, and go to 'first time to BMF?'. Then check to see if there is a session held near you.
You can either complete and print a form to take along with you, or arrive early to fill one out in person when you arrive.
BMF hold sessions in parks all over the UK, I had me free trial in Leeds, Roundhay Park - and it was very hard work, but I have since joined to become a member as it really does give you a full workout.
A great experience whether you go for just the free session, or if you go and sign up for membership.
