At home I do exercises like push ups, planks, elastic bands, and kettle balls. I have also built a pull up/chin up station. Since I live in a milder climate zone I ride my bike often on long rides for basic endurance and fun. That said i do go to the fitness center regularly.
Found a supper cheap easy to do at home workout doing a tri strength class using sliders (I use my wife's felt furniture movers from Home Depot). There are a hundred different lunges and push up variations you can do that just use body weight.
