Busy Schedule!

Hey,
was just wondering if anyone had an good, quick, easy and enjoyable little workouts or exercises that they could share?

ive recently had a baby so even though im not working atm im still pretty tied up in feeding and occupying a 5 month old. Im hoping to increase going for walks with the dog, but as i live in england is sometimes tricky as weather is rubbish and atm all its doing is raining! I could really do with some suggestions on little ways i can get a bit more exercise into my week???

Very grateful of any suggestions

Thanks x
