The best approach to fitness involves a mix of cardio and strength training. If you want to burn fat and build muscle, you will need to pay close attention to your diet. Your diet will determine how fast you get to see your results.
On the road to fitness, the best foods are Greek yoghurt, whole eggs, salmon, tuna, and chicken breasts and of course, brown rice. You can make yourself some healthy smoothies and add some whey protein to them. And it goes without saying, you need to eat lots of veggies like spinach, broccoli, sweet potatoes, carrots and beans.
