Tips for improving and optimizing overall health

So, I’m wondering if a person can actually sharpen their hearing.
Meaning, could I somehow train my ears to hear better or more clearly than my buddy does? If there's a way, what is it?

I'm also curious about training sight and smell.
And while we're at it, how do you actually build muscle? I don't hit up a Gold's Gym or anything, but a friend and I head to the local park once a week to run sprints and knock out some sit-ups and push-ups. The problem is, my arms are thin. Even though I eat like a horse, I can't seem to put on any mass. It’s honestly embarrassing—I'm not a twig, but they're definitely skinny. I basically overeat constantly and still gain nothing.

Anyway, if anyone could shed some light on this, I’d appreciate it.

Who is this?

You can't actually "develop" your senses. Not one of them. All you can really do is let them dull, which happens naturally as you get older anyway. Regarding your question about muscle growth, you'd be better off looking at a specialized fitness manual or an American Council on Exercise guide; you'll find much more professional, technical answers there. What I will tell you is this: don't expect anything from training just once a week. If you want results, you need to hit a solid workout at least three times a week. If your goal is bigger arms, you need to target them specifically—push-ups are primarily a chest exercise, so if you want arm growth, you should be working with free weights, like dumbbells. None of this matters, though, without a proper diet. You mentioned you overeat. What exactly are we talking about? If you’re binging on pepperoni pizza or processed deli meats, forget about building muscle. Simply put, you need to ramp up your protein intake for muscle synthesis and your carbohydrates for fuel, while cutting back on fats to avoid unnecessary weight gain. You should aim for at least 2 grams of protein per kilogram of body weight, spread out across five meals. It’s all about finding a balance, and honestly, it isn't easy. It takes real persistence and discipline.

What kind of protein should I be looking at? I’m a woman and I’ve always had incredibly thin arms—at least by female standards—so I really want to change that. I can't even pull a watch or a bracelet on my wrist properly. Everything just looks like it's hanging off me like I'm a skeleton, even though I'm not; I actually have a pretty normal body mass for my height.

Look, you can hit the gym all you want to build forearm strength, but don't hold your breath waiting for your wrists to get thicker. 🙂 I’ve got skinny wrists, plain and simple. Every bracelet I’ve ever bought, I’ve had to take to a jeweler just to size them down. And those high-end watches without the extra holes in the strap? Forget about it. They just slide right off. Believe me, I've tried both ends of the weight scale, but whether I'm gaining or losing, my wrist size stays exactly the same.
