Strength training: 6 ways to get more from your workout

1. Focus on form, not weight.

Good form means aligning your body correctly and moving smoothly through an exercise. Poor form can cause injuries and hinder strength gains because you aren't isolating muscles properly. "I often start people with very light weights because I want them to get their alignment and form right," says Josie Gardiner, master trainer and fitness consultant to Harvard Medical School and co-editor of the Workout Workbook. "It's good to start off using light to moderate weight when learning an exercise routine." Concentrate on performing slow, smooth lifts and equally controlled descents while isolating a muscle group. You isolate a muscle group by holding your body in the position specified for each exercise while consciously contracting and releasing certain muscles.

2. Tempo, tempo. Control is important.

Tempo helps you stay in control and avoid undercutting gains through relying on momentum. And sometimes switching speed — for example, lowering for three counts and lifting for one count instead of taking two counts for each — can enhance power.

3. Breathe.

Blood pressure rises if you hold your breath while performing strength exercises. Exhale as you work against gravity (when you're lifting, pushing, or pulling); inhale as you relax.

4. Challenge your muscles.

The optimum weight to use depends on the exercise. Choose a weight that tires the targeted muscle or muscles by the last two reps while still allowing you to maintain good form. If you can't do the last two reps, choose a lighter weight. When it feels too easy to complete all the reps, challenge your muscles again by adding weight (roughly 1 to 2 pounds at a time for arms, 2 to 5 pounds for legs); adding a set to your workout (up to three sets per exercise); or working out additional days per week (as long as you rest each muscle group for 48 hours between strength workouts). If you add weight, remember that you should still be able to do all the reps with good form and the targeted muscles should feel tired by the last two reps.

5. Practice regularly.

A complete upper- and lower-body strength workout two or three times a week is ideal.

6. Give muscles time off.

Strength training causes tiny tears in muscle tissue. Muscles grow stronger as the tears knit up. Always allow at least 48 hours between sessions for muscles to recover. You can always do "split sessions" — for example, you might do upper body on Monday, lower body on Tuesday, upper body on Wednesday, lower body on Thursday, etc.

Understanding Excessive Sweating: Hyperhidrosis

It's summer, and when it gets hot, our bodies sweat to help regulate our body temperature. But for some people, sweating in much greater amounts than necessary happens regardless of the temperature. This condition is called hyperhidrosis. In most cases, hyperhidrosis occurs for no apparent reason.

When it is focused on certain areas of the body, including the hands, armpits and feet, it is called primary focal hyperhidrosis. If hyperhidrosis occurs with other conditions, such as hypertension (high blood pressure) and hyperthyroidism (overactive thyroid gland), it is called secondary hyperhidrosis.

Primary focal hyperhidrosis affects 1 to 3 percent of the population. It affects boys and girls equally, with symptoms starting in childhood or adolescence.

How to recognize primary focal hyperhidrosis

When patients with primary focal hyperhidrosis begin to sweat, it is more than a mere inconvenience. Patients experience constant extreme sweating in the affected areas, with the sweat only stopping during sleep. It is worse in warm environments and when a child is stressed. Hands and feet are the most common places where the excessive sweating occurs.

Most children notice the intense sweating for the first time when their very moist palms begin to interfere with school and social activities. Excessive sweating in the hands can severely affect the ability to write, hold papers, use touch screens and hold objects. Many children are embarrassed by the condition and may begin to shy away from friends and social situations.
