Laura you should do some body weight circuits. They help build muscle and build up your cardiovascular endurance. Do each of the exercises in 30 seconds and transition
immediately into the next movement. Rest for 1 min and then perform the set 2 more time for a total of 3 times.

Jumping Jacks
Jump Squats
Pushups
Crunches
Mountain Climbers
Burpees

Hope this helps and good luck!

Hey fellas just as a suggestion I think everyone should watch this video featuring Jamie Oliver called Eat To Save Your Life. It talks about the general population in the EU and how so many people eat processed food. Its a good watch and it broken down into 8 parts. Be sure to watch the 8th part where they dissect a morbidly obese man. The over all idea of the show is to whole foods that is minimally processed.
