We've all heard it before: you've got to eat right if you want to be fit. But it doesn't take all out meal planning and hard core supplement stacking to get fit. All you need to do is eat whole, natural foods frequently and in smaller portions, if you're accustomed to eating in large amounts. That's it: we won't even tell you what to eat, really. Of course, to get the right assortment of nutrients and vitamins you should eat a variety of things. That includes fats, carbs, and proteins, with proteins being a priority. Don't listen to anyone who tells you to avoid any of those three things on some diet.
A Little Exercise Advice
If you do make it to the gym, there are a few things you can do that will prevent injury and overall just make your exercise easier. The first thing is to drink plenty of water, especially when working out, but throughout the day. If you're headed to the gym later in the day, you want to make sure you hydrated properly as early as the morning. Before hitting the weights, stretch and warm up. After sessions, cool-down gradually.
As far as techniques, if you're inexperienced or uncoordinated it will take some time to learn proper movements. No matter if it's weight lifting or aerobic exercises, follow the instructions of a personal trainer or someone who knows what they're doing. Always use a spotter when applicable so that you can challenge yourself with the weight. Check that the equipment you're using is safe before using it. And lastly, less is more: rather than over-train your muscles, stick to a thoughtful regimen. It'll help you avoid killing your own performance and enthusiasm.
