A superset involves doing two or more exercises that target the same muscle group, back to back with minimal rest in between. For example, doing a set of 12 heavy squats followed by a set of 12 heavy lunges is a superset. The drawback to this technique is that you will not be as strong as you usually are on the second exercise. However, this is a great technique to pre-exhaust a muscle and really isolate it.

According to the American Heart Association, if your heart rate is too high, you’re straining. If it’s too low, and the intensity feels “light” or “moderate/brisk,” you may want to push yourself to exercise a little harder. During the first few weeks of working out, aim for the lower ranger of your target zone (50 percent). After six months or more, you may be able to exercise comfortably at up to 85 percent of your maximum heart rate.

Since the heart is a muscle, it can become bigger and stronger through exercise that progressively increases the body's demand for oxygen. A well-conditioned heart can actually beat as few as 40 times a minute at rest compared to the normal heart that beats at a rate of approximately 70 beats per minute. This allows it to conserve energy and supply oxygen-rich blood to the rest of the body with half the effort.

Sports shoes are among the most important piece of fitness equipment you’ll buy, so it's important to pick the right pair. Even if they still look fine, you should buy new shoes about every three to six months or 300 to 500 exercising miles. Choose them later in the day when your feet are larger, and consider the advantage of buying from a store that specializes in athletic footwear, and whose staff will be able to offer in-depth advice.

The study showed that the concentration curl activated the biceps muscles more, and the anterior deltoid muscles less than the other exercises.

Even those with strong motivation and an organized workout routine suffer setbacks. Life isn't always predictable, whether because of an injury, a family emergency, or just feeling low in energy. Experienced workout enthusiasts know it’s crucial to accept the need for a temporary lowering of expectations - to make adjustments, and have patience, and not to let minor setbacks develop into a long term layoff.
