Cardio vs. Weights
Cardio is the only exercise that may help prevent heart disease.
- True
- False
Cardiovascular exercise, also called cardio or aerobic exercise, raises your heart rate and makes you sweat -- and that’s great for your ticker. Regular cardio, whether it’s jogging, cycling, swimming, or brisk walking, will make your heart stronger. It also helps with blood pressure and cholesterol, and can even help ward off some cancers. Weight lifting --even for one hour per week -- also reduces your risk for heart attack and strokes.
Aerobic means:
- “With air”
- “Fast heart”
- “Quick breath”
Your heart’s main job is to deliver oxygen to your body. Aerobic exercise, also called cardio, helps it do this better. It includes any activity that makes your body need more oxygen, like jogging.
Adults should get at least this much cardio each week:
- 2 hours
- 2 1/2 hours
- 3 1/2 hours
That’s 150 minutes of any exercise that makes you breathe harder and revs up your heart rate. Break it up any way you’d like -- do 30 minutes a day, 5 days a week -- just be sure to move for at least 10 minutes at a time. Can’t get to the magic number? Do what you can. You’re still doing your body good.
People with muscles burn more calories.
- True
- False
Your muscles burn calories even when you’re not working out. So the more muscles you have, the more calories you’ll burn. If you work out with weights often, you’ll also lose fat and look slimmer. Want to turn your bod into a lean, calorie-torching machine? Reach for the dumbbells or hop onto a machine that uses weights.
You don’t need strength training if you do a lot of cardio.
- True
- False
Cardio is king when it comes to your heart, but strength (also called resistance) training does wonders for your bones and joints. Get in at least two sessions a week and work your legs, hips, back, abdomen, chest, shoulders, and arms.
Which is better for you?
- Cardio then weights
- Weights then cardio
- It depends
What you tackle first depends on your goals. If you’re training for a 5K, start with cardio. Your muscles will be warmed up, and that may help prevent injuries during strength training. If you’re focused on strength, hit the weights first. Pumping iron before cardio could make you stronger and more toned.
Which lowers your risk of dementia?
- Cardio
- Weights
- Both
Whether you swim, run, power through pushups, or use a leg-curl machine, you’re doing something good for your brain. Cardio and strength training can both help you think more clearly and improve your memory.
Weight training might help keep you from falling when you’re older.
- True
- False
Using weights not only reduces your risk of heart attack and strokes, it can also lower your chances of osteoporosis, a disease that weakens bones and makes you more likely to break a bone if you fall and have fractures. Training with weights strengthens your bones and muscles, helps with your balance, and can make daily tasks easier as you age -- like climbing stairs, getting out of a chair, or lifting groceries. Other weight-bearing exercises, like walking or dancing, can help with this, too. Having strong muscles from exercise can also help prevent falls.
It’s best to go at least this long between strength training workouts:
- 24 hours
- 48 hours
- 72 hours
When you lift weights, you get small tears in your muscles. Your body needs time to recover before you lift again. You can keep up the cardio, though.
You should switch up your weight training routine:
- Every 4 to 6 weeks
- Every 6 to 12 weeks
- Every 6 months
You’ve got to keep your body guessing to get the biggest gains. Changing things up will make you stronger and help prevent injury. If you’re a little bored with your workouts, try different exercises, use heavier weights, or vary the number of repetitions you do.
It’s best to lift weights:
- Slow and steady
- As fast as you can
- Slow first, then faster
Rushing through your reps can lead to injury. Instead, focus on good form. Don’t jerk the weights or use too much force. If you haven't done much work with weights, get some tips from a trainer. For example, remember to breathe. Breathe out as you lift the weight, and breathe in when you lower it.
