This sounds sort of stupid, but it's harder than you may think. Basically run in place, but bring your knees up to about your chest (it helps if you hold your hands in front of your chest and you hit them with your knee each time you jump up) for a set amount of time. It's actually quite tiring. Since you're in an apartment and your lower neighbors might not enjoy that activity, you might want to go outside nearby and do it, but give it a try, it could work out quite well for you.
