People are always asking me ways to work out should they be stranded outside civilization somewhere.Without electricity, machines, and television sets, a lot of people just don't know what to do. You can lose 20 pounds without anything but you.
This sounds like it's somewhere in the jungle, but it can also be similar to the conditions at a hotel or at home. The good news is that you can build muscle and improve your body composition without any equipment.
The simple fact is that the mass of your body can be leveraged to your advantage. Here's a good example of a good workout that you can build on for your own routine.
One: A high movement activity like side-straddle-hops or in-place running.
#2 - Squats with each hand in back of the neck to help your back's higher section.
#3 - Simple push-ups done from a kneel or from a standard position. Get some more suggestions from a weight loss forum.
Four: 1-leg routines such as the lunge.
#5 - Work for the back's high section via the pull up, chin up, inverse row, or rowing with DBs or bands.
#6 - A different 1-leg routine like a splitting squat.
Seven: Abs movements that involve the entire body. Climbers are a possible choice.
Eight: Choose a quick moving drill like burpees, jumpropes, or sprints to wrap up.Perform all eight categories without pause so it's a continuous series with a set count for each.
You should repeat this series 2-3 cycles. You want to make sure you get a good workout that stresses your body, but you don't want to overdo it either. Assuming you make an honest effort at this sequence, someone who is new to fitness should limit themselves to one cycle until you get acclimated.
You won't need to be stuck on an island to benefit from this kind of routine: you can do it right now. You'll also enjoy experiencing rapid weight loss.
