When your schedule is packed, you want to make your gym time count. Well, what if you were able to double your normal results and get to your goals in half the time? Well, that is absolutely possible if you follow just a few simple workout guidelines.They are:Vary your intensity. If you are exercising at the same level of exertion each and every time you work out, you’re likely not experiencing the best results. To burn more calories and experience greater fat loss and muscle gain, you’ll want to vary your intensity several times during your workout session. This keeps your body guessing (so it doesn’t plateau) and your metabolism will stay elevated for longer even after your workout has ended.Incorporate strength training in your routine. Don’t shy away from building muscle because muscle burns many more calories than fat, allowing you to lose weight even when you’re being inactive (think sleeping or sitting in front of the computer). If you don’t like using free weights, try resistance bands for the same positive effects and a multitude of different workout options.Fuel up properly. You won’t work out very hard and burn a lot of calories if you’re running on empty. Therefore, you’re going to want to fuel your body before your exercise session so you can work it harder and longer. Some great pre-workout choices are a banana with peanut butter, a protein shake, and Greek yogurt.Hydrate, hydrate, hydrate. Your body needs water to have a high metabolism, so you’re going to want to make sure you get enough of this quality beverage before, during, and after your workout. In fact, if you are thirsty then you are already dehydrated so keep your water bottle handy all day long to ensure that you never reach that point.Do these four things and you are on your way to burning more calories (and more fat) with your exercise sessions. After all, if you’re going to put in the time in the gym, you might as well make it worth it, right?
