Are you concerned about your body weight? I have found this tabata body weight loss workout effective quite easy to carry out. This 25 minute workout requires no equipment. You can do it whenever and wherever you can.
Just do each exercise for 20 seconds, rest for 10, and move to the next movement. Repeat all the exercise 8 times. That takes about 25 minutes. Do it every day, and you should start seeing the results in a couple of weeks.
