This metabolism booster will keep your heart rate up to burn calories while building lean muscle. You’ll get breathless with cardio-intensive moves, but remember: This workout is only 20 minutes, so give it your all!
These workouts have really helped me increase my endurance. I have never done cardio workouts before discovering popsugar and in just a few months of doing the cardio workouts my fitness level has gone way up. I can do more pushups, hold planks longer and I have more energy all around.
If you are reading these comments I would love to see popsugar do a workout bundle focused entirely on increasing muscle strength and endurance (a serious weight workout that takes you up in weight intervals over time).
