Exercise is fundamental to my happiness. There have been plenty of days when my husband asks me in his sweetest voice if I need to go for a run. Maybe he should be asking me if I want to lift weights. Muscle helps your blood pressure return to normal quickly after a stressful event, which at our house can be trying to get two tired little girls to brush their teeth before bed. In contrast, fat can slow down the process of lowering your blood pressure. Strength training, be it lifting weights or doing push ups will not only help relieve stress in the short-term, but the muscle you build might just help you calm down faster later.
