Add strengthening exercises to your walking workout to build muscle. Even though strength training does not burn considerable calories, it replaces your fat with lean muscle mass. Your body works harder to sustain your muscle mass, raising your resting metabolism so you burn more calories throughout the day. Invest in light hand weights or wrist weights and pump your hands as you walk. Build lower body muscles by lifting your knees high during part of your walk. Stop every five minutes and do a series of squats or lunges.
Meta-analyses and reviews are useful for getting an overall sense of the many studies of aerobic exercise and BP. A 2007 meta-analysis of the effects of endurance exercise on BP found that exercise significantly reduced resting and daytime ambulatory BP.38 A more recent review (2010) found again that regular aerobic exercise lowered clinical BP.39 In both the 2007 meta-analysis and the 2010 review, aerobic exercise appeared to reduce BP more in patients with hypertension compared with those without hypertension. Five small studies in women systematically reviewed in 2011 showed a nonsignificant change in BP in response to aerobic interval training of walking. Walking programs appeared to reduce BP in some 9/27 trials reviewed in 2010. Larger trials with increased intensity or frequency of exercise for longer periods tended to be the ones that showed a significant effect.40 The authors concluded that further high-quality trials are needed. The most comprehensive and latest meta-analysis of all types of exercise clearly demonstrates the ability of aerobic exercise to lower BP within 8 to 12 weeks.41 In 105 trials, endurance exercise significantly lowered BP by 3.5/2.5 mm Hg. The effect was much larger in patients with preexisting hypertension (−8.3/6.8 mm Hg).
4. It eases joint pain. Several studies have found that walking reduces arthritis-related pain, and that walking five to six miles a week can even prevent arthritis from forming in the first place. Walking protects the joints — especially the knees and hips, which are most susceptible to osteoarthritis — by lubricating them and strengthening the muscles that support them.
