Let's talk about two of the biggest buzzwords fit-freaks like to toss around: cardio and strength training. We all know that both are essential for your well-being, regardless if you're a muscle-bound machine, a park-run enthusiast, or a random person who just wants to fit into that Christmas sweater without popping any seams. Each type of exercise can play a pivotal role in your overall health and fitness, and, spoiler alert, you don't have to favor one over the other – variety is the spice of life, after all.

The whole point of cardio (a.k.a. aerobic) exercises is to give your ticker a thorough workout. By raising your heart rate and boosting the amount of blood your heart pumps with each beat, you strengthen your heart muscle and boost your endurance. Why do you often feel like you are about to keel over when doing cardio? Simple - these activities demand more oxygen, thus making you gasp like a fish out of water. But hey, that's all part of the fun, right? If you're feeling adventurous, examples of cardio exercises include running, swimming, cycling… you know, the usual stuff that makes you question why you ever left your couch in the first place.

Strength training, on the contrary, is all about mastering resistance to chisel those muscles across your body - arms, legs, back, neck, and, most importantly, that coveted six-pack region. Whether you're pushing, lifting, or pulling weights, or just fighting against good old gravity, this form of training can be thrilling or utterly torturous, depending on your mood.

News flash - many exercises are a potluck of both strength training and cardio. Ever thought weight training gets your heart-rate up? Or that cardio can help build muscles throughout your body? But yes, there's a catch…the amount of cardio or strength training you get out of these exercises depends on how fast or slow you do them and even how long you hold positions.

Of course, let's not forget the cherry on top - these exercises come with an array of benefits. Cardio, as we’ve touched on, revs up your heart's efficiency and helps ward off cardiovascular disease. Strength training, on the other hand, helps maintain your muscle strength (obviously) and promotes bone health - which is pretty handy, considering you'd like your skeleton to, you know, stay intact.

What’s the ideal dose of exercise per week? Just follow the CDC's guidelines: cardio should be part of your schedule throughout the week, while strength training should be done on a minimum of two days per week. And for those over 65, it's essential to add in a couple of balance exerciseseach week. Before you engage in any advanced fitness regimen, make sure to check in with a healthcare provider to avoid biting off more than you can chew because, let's face it, waking up unable to move isn't as fun as it might sound.

So there you have it. Cardio and strength training are both important pieces of the puzzle when it comes to leading a healthy lifestyle. One isn't inherently superior to the other; instead, they are the dynamic duo of fitness. In essence, strike a balance between both - it will keep your body guessing, your workouts interesting, and, more importantly, consistent. After all, "variety," "moderation," and "consistency" may not have the same ring as "Eat Kale Or Die Trying," but don't underestimate them. They're the true recipe for a fitter, healthier you.
