Sometimes it can be hard to tell the difference between allergies and the common cold. There are more than a hundred strains of cold viruses. Each tends to become widespread at certain times of the year, which is why you may mistake a cold for a seasonal allergy.
Q: How often should I work out? A: The amount of exercise you need depends on the type of lifestyle you want to maintain. For beginners, most experts recommend at least 20 minutes of exercise three times a week. These 20 minutes can be a combination of four 5-minute sessions of exercise, two 10-minute sessions or 20 continuous minutes. Just doing something is better than no exercise at all.
Unlike what you may read about in the muscle mags, you do not have to train hours a day, seven days a week to get results. In fact, any more weight/resistance training than 2 to 3 hours a week may be counter-productive. The best results I've witnessed while in the personal training field come from 3-5 sessions a week with weights, less than an hour each session.
