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.
Maybe you could start with smaller bouts of exercise instead of 50 minutes. Start walking for 5 minutes per day and as you feel stronger increase to 10 and so on. Make sure you eat something about 30 minutes before exercising, like a banana, yogurt or granola bar. If you are low on glycogen (stores of carbohydrates in muscle), it could increase your tiredness after exercise. If you continue to feel tired without a good reason, visit your healthcare provider for a full blood work-up. Certain nutrient deficiencies, like anemia, can also make you tired.
