If you struggle to fit movement into your day, a walking workout could help you do more than just increase your step ...

So, if you know you won't be able to do your regular workout due to an early morning meeting, taking a 15-minute walk on your lunch break or after dinner could get you the same benefits.

Do 10 to 15 repetitions. (Note that you may use substantially less weight for this than for curls or chest press.) Advanced: Eventually try building up to this 3-minute routine. Pull-ups.
