Building Big Arms

img_5792

Most men seem to fall into one of two camps when it comes to arm workouts:

Guys who do chin-ups (complex exercises that work multiple muscles), and guys who do curls (isolation exercises targeting a single group).

Complex movements are functional and great for people beginner and intermediate lifters, but may not deliver the pure muscle size you want. On the other hand, isolation exercises are great for hypertrophy but not function, meaning they’ll pack on some muscle, but won’t necessarily help your total body strength. Combine the two, and you get the best of both worlds.

Look at your isolation exercises and complex movements as lobster and steak: Each is good on their own, but together they’re unstoppable. Workouts that have curls and chin-ups, or bench presses and tricep pushdowns, are more likely to deliver both the size and strength you’re looking for.

Determining a Calorie Deficit for Weight Loss

img_4834

A pound of fat equals 3,500 calories, which means, to lose 1 to 2 pounds per week, you need to burn off 500 to 1,000 calories more per day than you consume — or between 3,500 and 7,000 calories per week. Losing weight fast isn’t recommended by most major health organizations — it’s usually unsustainable and can lead to nutrient deficiencies, muscle loss and a stalled metabolism.

Use an online calculator to determine your daily calorie needs, given your current age, size, gender and activity level. Add exercise without increasing your calorie intake. If you eat more calories in response to exercise, it won’t result in weight loss. For example, a 155-pound person burns 2,000 calories per day and eats 2,000 calories will maintain her weight. But, if she exercises and burns an extra 500 calories per day — perhaps by jogging at 5 mph for 45 minutes — but continues to consume 2,000 calories, she can lose a pound per week.

Exercise helps burn calories and also maintains lean muscle mass while you’re losing weight. If you reduce calories without exercise, one-quarter of every pound you lose comes from lean muscle mass. Muscle also requires more calories for your body to sustain, so it boosts your metabolism. A more muscular body also looks taut and fit.

Measure the benefits exercise provides to weight loss in more than just calories burned, too. Cardiovascular exercise, which involves raising the heart rate for an extended period of time, such as cycling or running, burns a lot of calories per minute as compared to strength training. But, strength training is better at developing muscle mass when compared to cardio.

You may burn just about 100 calories per half-hour session of strength training but reap numerous, additional benefits. Ten weeks of resistance training can increase your lean muscle mass by 3 pounds, decrease your fat weight by 4 pounds and increase your metabolic rate by 7 percent, reports research published in a 2012 issue of Current Sports Medicine Reports. A balanced approach to exercise that includes both forms is best for your health and weight loss.

Building Muscle on a Calorie Deficit

Because the human body is designed to sacrifice muscle when losing weight as a survival mechanism, only a certain body type will permit the simultaneous growth of muscle and loss of overall mass. If you’re significantly overweight, your body may be able to support increased muscle mass even on a caloric deficit, provided it has less fat to maintain. If you’re relatively lean and/or muscular, however, it is much more difficult for your body to increase muscle mass while experiencing a caloric deficit.

While a caloric deficit implies that you’re eating less food overall, it is possible to increase your protein intake during a caloric deficit by adjusting your diet to include more protein-rich foods. To succeed in building muscle and losing weight simultaneously, consume 1.6 g of protein per kilogram of bodyweight daily. To meet this goal, you’ll likely have to rely heavily on protein sources, such as meat, fish, beans, eggs and tofu. You may also consider a powdered protein supplement.

To build muscle while losing weight, you’ll have to train with a high degree of intensity. Since the body’s natural inclination is to sacrifice muscle when losing weight, training is the only way to provide a stimulus that lets your body know that muscle is needed. To maximize this stimulus, focus of heavy, compound exercises, such as the bench press, shoulder press, bent-over row, squat and deadlift. For each exercise, perform three to four sets of eight to 12 repetitions for maximum muscular hypertrophy potential.
