Walk to work
Walk to the office, ride your bike or at least take the stairs. You get the idea. It's naive to think that men everywhere have the time, patience and commitment to exercise frequently enough to maximize physical fitness. The solution then is to improvise. Whether it's reciting a presentation while on the treadmill or watching your favorite show while doing sit-ups, find a creative way to fit physical activity into your day. It's the one healthy habit that will forever ensure that you're always primed, ready and raring to go regardless of what physical challenge is put in front of you.
