Orangetheory Fitness is a group workout franchise built around heart-rate training. Participants wear a chest-strap or armband heart-rate monitor during a roughly one-hour class, and a screen at the front of the room shows each person’s effort level in real time. The goal is to spend a set amount of time in a high-intensity zone, … Read more

A cardiovascular accident is the older medical term for what doctors now call a stroke — a sudden loss of brain function when blood flow to part of the brain is cut off or a blood vessel in the brain bursts. The brain needs a constant supply of oxygen and glucose, and when that supply … Read more

Rowing is one of the most effective forms of cardiovascular exercise available. It uses roughly 60% of your body’s muscle mass in a single continuous motion, which drives heart rate up quickly and keeps it there for as long as you keep pulling. Whether you row on water or use an indoor ergometer, the cardiovascular … Read more

Period cramps happen when the muscular wall of the uterus contracts to help shed its lining. The squeeze briefly cuts off blood flow to the muscle, and that temporary lack of oxygen is what you feel as pain. You can ease most cramps with heat, gentle movement, over-the-counter pain relievers taken early, and a few … Read more

The core principle is simple: strength is built by moving heavy weight with good technique, not by chasing a burn or a pump. You do fewer … Read more

Two people start the same walking program on the same day. One is still walking a year later. The other stopped by week three. Their bodies were not the difference. Their habits were. Behavior is the single largest thing you control when it comes to physical fitness — it determines whether you exercise at all, … Read more

A workout split is simply how you divide your training across the days of the week. Instead of working every muscle group in every session, you assign certain muscle groups or movement patterns to certain days. A common example is training the upper body on Monday and Thursday and the lower body on Tuesday and … Read more

Your muscles run on fuel, and what you eat decides how much of that fuel is available, how quickly it gets delivered, and how well your body uses it. Nutrition affects exercise performance by supplying carbohydrate for high-intensity work, protein for repair and adaptation, fluid and electrolytes for temperature control, and micronutrients that keep energy … Read more
