Q. Hello, Miss Fitz! I think my best shot at getting fit would be to train at home. What size weights should I buy? I'm a 32-year-old woman, and I'm about 20 pounds overweight. Thanks! Alyssa

A. Thanks for writing, Alyssa. I'm glad you're getting serious about becoming more fit, and training at home is a really great place to start! Honestly, since I'm not standing next to you assessing your fitness level, it's almost impossible for me to tell you exactly what weights you should be using. However, I can provide you with a range, and I'm fairly confident they'll meet your needs.

The first thing you'll need to understand is that there will not be a "one-size-fits-all" weight. You're going to have to invest in a few different sets to meet all of your needs. The larger muscles of your chest and back are often far stronger than your biceps and triceps. I, for example, can lift more than 160 pounds while performing a "row," which is an exercise for the back. I can only curl 20-pound dumbbells in each hand to exercise my biceps, though.

As a generic kick start, I'd like to recommend you purchase a set of 5, 10, 12 and 15-pound dumbbells. Of course, these won't be appropriate for everyone, but my experience training about 100,000 people over the years tells me they are a smart start. Choose lighter or heavier weights if these choices are inadequate. I'd recommend sets of 15, 20 and 25 for a male beginner. And I must preface all of this by letting you know that these recommendations are for the average and completely healthy adult. Those with injuries or illnesses should consult a local professional for personal guidance.

I have a few more suggestions for you to consider:

• Check out PowerBlocks. PowerBlocks are adjustable weights you can store in small places.
• Take a look at my Fit Kicks with Fitz video series if you're not sure exactly how to lift weights properly.
• Start slowly and graduate to a weight that challenges each muscle group. If you're forced to grunt a bit, yet can still maintain proper form, you're on the right track.
• Allow 48 hours of rest before you work a muscle group twice.
• Use a "spotter" if you're lifting weights over your head. A spotter is a person who can offer support if you lose control of your weights.
• Listen to your body. It's fine if a weight feels difficult to lift. It's not fine if an exercise causes you sharp pain. Know the difference.
  
• Try out resistance tubing. One tube can offer the perfect amount of resistance for total body training. It's also perfect for strength training on the go.

Work hard, grow stronger and enjoy the immeasurable benefits of a more powerful and resilient body. Now get to work!
