Strength training is much more than quickly lifting a few weights.
Aerobic exercise, such as running or using a stationary bike, makes your muscles use more oxygen, strengthening your heart and lungs. For instance, when you do a bicep curl , raising a dumbbell up to touch your shoulder with your arm starting at a 90-degree angle, you isolate the muscle group known as the biceps. With a weight machine known as a leg press , you sit in a reclining position with your knees bent up against your chest to start. Most gyms or weight rooms set up their machines in a circuit , or group, of exercises that you perform in a certain order to strengthen different groups of muscles. For specific medical advice, diagnoses, and treatment, consult your doctor.
