During the holidays most of us manage to pack on a few extra pounds, because we like to enjoy ourselves when we are socializing with our friends and family members. Who can pass up those especially delicious desserts that are served up to celebrate the holidays? After the holiday feasting we need to take effective action to remove the weight we have added during the holidays. Amazingly enough we can achieve our goal of returning to our pre-holiday weight without resorting to drastic measures. Aerobic exercise is generally one of the means folks can employ to take off some of the fat they packed on during the holidays. For seniors walking or bicyling are fine exercises, but it turns out that walking or biking using the interval training approach provides a more rapid amount of fat-burning. In the interval training approach folks walk or bike a nearly their fastest pace for about 2 minutes and then walk at a slower pace for 3 minutes. This interval training type of walking apparently increases the amount of fat-burning enzymes. Compared with straight brisk aerobic walking or biking at about 70% of maximum heart rate, interval walking or biking folks lost nearly nine times as much fat and the fat-burning effects lasted for 24 hours. This is good news for seniors who are trying to take preemptive aging steps to enhance their senior health by participating in cardiovascular activities.
