I like the 30 day challenges. For the first week or 2 you can knock them out in the office. After that you need to be home (espcially the ab challege) b/c you tend to sweat. I did ab and squat last month. You gradually build up and it is a great way to get motivated. On day one a 120 second plank seems impossible but you can get there.

Stairs are also a great idea. Free and convenient as long as you don't work from home

In your office: push ups, mountain climbers, lunges (hold a book over your head for increased stability challenge).

Is there somewhere you could set up stretch cords or a TRX?

Run the stairs. Jog in place with high knees. Old school jumping jacks.

I like the Ballet Beautiful videos. Everything is in 15-minute segments, so I just do them throughout the day when I have time. I've always been a cardio person but had to stop due to injury. These low-impact exercises have improved my body in a way that running never did. Waist got smaller, shoulders more defined--I look more like I did pre-kids. You can stream them on your computer or just buy the videos. I get them for free with Amazon Prime. And I'm not a sweaty mess so I don't have to shower each time.

Jumping rope
Plyometric exercises?
Agree with stair climbing/running

That is a terrible attitude, and probably why so many people are so sedentary. The OP didn't even mention burning fat, perhaps he/she wants to improve health?

OP, I walk the stairs in my office building when I have breaks. Sometimes I'll close my door and knock out some push-ups, too. Squeeze more in whenever possible!

I'm fairly certain there have been quite a few studies that show that 15 minutes IS enough for health-improving benefits.

The Daily HIIT - tabata style workout designed to do at home, and at least the beginner / older workouts (back when it was BodyRock) were 12 minutes - 3 rounds of 4 exercises at 50sec on / 10 sec rest. But even though this is short it is definitely a get sweaty set.

there's a guy in our office who climbs the stairs at lunch (we go up 7 floors). 15 minutes of stairs 2x/day would work your heart rate and legs.

Squats, lunges, pushups, plank... repeat. Easy to do in your office.

A 20minute run (powerwalking and running in intervals) would be great.

yeah, but getting up a few times a day for 15-minute walks is better than sitting for 8 hours straight.

first of all, it's better for your circulation.

Do you have stairs in your office? If you run those for 15 minutes, you are getting a great workout.

Try Tabata - it's a type of high intensity interval training,. Definitely can't do it in your office (anything you can just do in your office isn't like to do much for you anyway!) Here is a basic explanation:

but if you Google it you'll find specific Tabata routines. Super simple, super short, great workout.

I'm letting the best be the enemy of the good. I can't find time to work out, so I'm not doing it. But I'm thinking over the course of the day, I could fit in some short bursts of exercise. Does anyone have suggested short workouts? Nothing more than 15 minutes--even the 30 day shred really takes closer to 30 minutes until I get it set up. Bonus if it's something I can do in my office. I have to get off my rear and start moving!
