4 Tips to Fire Up your Metabolism:

1. Do interval training – periodic fast-paced intervals raise your metabolic rate higher than a steady cardio workout can. 
2. Drink green tea – this really does impact on your metabolic rate. Some green teas are quite bitter in taste, so find one you like and drink 3 cups a day!
3.  Build more muscle – lean muscle mass acts like a furnace and helps burn body fat effectively. The more muscle you have, the better the fat burner you are.
4. Pick up heavier weights – we are never to old to challenge our bodies with weight training. Progress to lifting heavy weights at a slow rate. This causes minor tears in the muscle, which repair and grow if provided with the right amount of protein and recovery time. Your metabolism gets a boost while the muscles repair.
