8 Simple Ways To Burn Stomach Fat FAST

# 7: Vertical leg crunch
The vertical leg crunch is similar to a regular crunch. But it requires you to keep your legs straight, which makes the abs work harder and increases the workout’s intensity.

-Lie down with hands behind your head
-Put your legs straight up with knees crossed
-Flex abs to lift head and shoulders off the floor
-Lay back down
-Keep legs extended in the air the whole time
-Exhale when you flex; inhale when you lay back down
-Do 1-3 sets with 12-16 repetitions
