If you have high cholesterol levels and consider yourself to be a coach potato, start slow by walking and then work up to more intense aerobic exercises.
How aerobic exercise lowers your bad cholesterol — that’s the LDL numbers — is not totally clear. What we do know is that “exercise has been shown to increase levels of enzymes that remove bad cholesterol from the blood,” said Victoria Shin, MD, interventional cardiologist, and chair of cardiology at Torrance Memorial Medical Center. “And exercise has been linked to a consistent increase in the HDL (that’s our good cholesterol) with moderate decreases in triglycerides and LDL (that’s our bad cholesterol).”
If you’re confused about good versus evil (that is, bad cholesterol levels), here’s a quick lesson. LDL, our bad cholesterol, clogs our arteries with plague. This can lead to a heart attack or stroke. HDL, our good cholesterol, cleans out the bad LDL from our arteries and can protect us from heart attacks and strokes.
Your doctor can tell you how much good and bad cholesterol is in your body via a simple blood test. Your total cholesterol levels should be less than 200. Your LDL should be less than 100 and your HDL level should come in at 60 or greater.
How to lower your cholesterol
Exercise can improve the good and lower the bad cholesterol levels. “Both aerobic exercise and resistance training work in conjunction to improve cholesterol profiles,” Shin said.
Shin suggests race walking, jogging, running, swimming laps, hiking uphill, playing tennis, and spin class. If you are new to exercise, start slow and consult with your physician. Overdoing aerobic exercise is the fastest way to burnout, and you could hurt yourself.
So, if you consider yourself a coach potato, start slow by walking and then work up to more intense aerobic exercises. These exercises can lower your bad (LDL) cholesterol levels if you do them three to four times a week for 30 to 40 minutes.
Shin also recommends jumping rope. At a moderate rate, you can burn between 10 and 16 calories a minute. Start with three 10-minute intervals. A 10-minute round of jump rope equals running an 8-mnute mile.
Cycling is another favorite activity. The benefits are numerous and include increased muscle strength and flexibility, improved joint mobility, decreased stress levels, and increased bone strength.
You can also try rowing, which offers you a total body workout. It works your quads, hamstrings, glutes, lats, core, shoulders, triceps, back, and biceps.
If you like the outdoors, cross-country skiing will give your body a total aerobic workout. It also strengthens and improves your heart health.
If you want to work out with a partner, try ballroom dancing or just turn up the music at home and dance. With good lively music, you’ll have fun while you’re improving muscle tone and strength. Dancing also builds endurance and motor fitness, burns calories, benefits your heart and lungs, and builds strong bones, thus reducing your risk of osteoporosis.
While these exercises are good for your heart health, Shin says that adding resistance training is beneficial, too. It’s also known as strength training and uses machines and free weights that you’ll find at a gym or health club. Resistance training also lowers high blood pressure and helps to improve diabetes.
Resistance training also helps develop muscle strength and endurance, lowers blood pressure, can prevent injuries to your bones, and controls your blood glucose.
Shin sees aerobic exercise and resistance training working together. Start with moderate aerobic exercise and transition to strength training. The repetition and stretching are also good for your heart and muscles.
Just be sure not to lift too much weight or overdo strength training or any type of exercise. That does more harm than good. And always talk to your doctor before you start a new exercise program.
