Doing circuits are a great way to incorporate strength at home. You can make up your own by doing a minute each of exercises such as pushups, squats, burpees, tricep dips, jumping jacks, etc. then repeating the sequence. I'd also suggest googling circuit training workouts that don't require equipment. You can also find tons of videos on YouTube as well!
Here is a great list of some examples: www.pbfingers.com/2012/01/15/at-home-worko
And here is one of my favorite treadmill strength training combo workouts www.nordictrackcoupon.com/articles/using-d
Hope these help!
