5. Wind Markers: Mark a starting line on the round, then mark four points out in front of that line, each approximately 10 yards apart, for a total of 40 yards (an approximation is fine). Start in a sprinting position at the starting line. Sprint out as fast as you can to the first marker, then turn and sprint back to start. Repeat this out and back pattern to each line. After you’ve returned from the fourth line, perform 4 burpees, then 4 push-ups. That’s 1 round. Complete 7 rounds as fast as possible.
There are a variety of definitions of what moderate-intensity exercise is, but it typically falls between about 70 to 80 percent of your maximum heart rate, which would be a level 4 to 6 on a 10-point perceived exertion scale. That means you are breathing harder than normal but can carry on a conversation without much difficulty and you feel pretty comfortable with what you're doing. The American College of Sports Medicine (ACSM) often recommends this level of intensity in its exercise guidelines. The lower end of this range usually incorporates the fat burning zone.
