Lifting and Cardio

Can lifting increase ones cardiovascular abilities? Well the short answer is yes. The kinda long one is yes and no. And by that I mean it doesn't actually strengthen your heart much or expand your lungs, however it will increase your overall endurance. So by adding that extra muscle to your legs,core, or wherever; you'll be able perform your daily or weekly cardio at a faster pace or longer distance  whether that's running,swimming,biking,or wrestling your kids in their car seats...because your muscles don't and will not fatigue as easily. Why's that? the main reason your body fatigues during an aerobic exercise is your muscles are tired of repeating that movement over and over and over again. The fix; work on strengthening your muscles three times a week. That's it, just three times a week and you'll have drastic improvements in a matter of weeks. Of course there are some of us who don't have access to a gym or weights at home, If that's the case for you, get creative, you don't have to lift weights to strengthen your body. So hit up your local park that has an obstacle course, or just knock out some body weight exercises.
