If no candidate wins by an absolute majority in the first round, a second election round is held between two candidates with the most votes. The last presidential election was in 2012, and the next is expected in 2018.
An effective way to cool-down after exercise is to perform 5-10 minutes of low-intensity activity such as cardio or flexibility exercises such as foam rolling and/or static stretching. Low intensity cardio will help to bring down the body's heart rate to a more rested level after the workout.
When you exercise your leg muscles, they will grow a little, but you will mostly see the effect immediately after exercise as the muscles swell to bring in nutrients and expel waste. This effect goes away after 30 minutes to an hour. As the muscles recover, they build new fiber and also use it more efficiently. The result is unlikely to be visible as a larger muscle, but rather a leaner, toned muscle. If you exercise enough and watch your diet, you will lose fat as you gain muscle.
