I frequently get asked how often I workout and most people are surprised when I tell them about 3 days a week. Sometimes I go to the gym near my house, sometimes I workout at home and sometimes I'll do a few things at my training center. I don't workout as often as people think at my facilty simply because it's hard to stay focused when others are asking questions or needing something. Not that it's bother but it's hard to get into the groove. My workouts don't last more than an hour and sometimes I knock them out in 30 minutes or less.
At home I have bands, dumbbells, med balls  ;and a stability ball. I do a lot of functional and strength training with the gear that I have. I also have a treadmill where I do interval training. Going slow for a minute then fast for a minute and continuing for several repetition s.
At the gym I like to hit the heavier weights and target specific muscle groups.
At my facility I like to do some of the sports perfromanc e drills that we do with our athletes such as box jumps, agility ladder (gotta keep up with the youngsters ), dumbbell work, power work etc.
In case you haven't figured it out, I don't have a specific training regimen that I stick to or follow. By doing a combinatio n of differnt things throughout the week, my body gets all the exercise it needs to stay fit.
A little over a year ago we got a black lab puppy (Jazz). One of my favorite things to do now is to take her on a run 3-4 times a week. I don't really count this as a workout because we only run about 2 miles with some stops in between if you catch my drift. I turn these runs into intervals. I warm jog for the first 5 minutes and then sprint for about 20-30 seconds at about 80-90% of my top speed. Then we walk or slow jog for 30 seconds and then sprint again. We continue this until we make the turn back home and cool down. These runs are great because it gives Jazz a chance to run hard and get some exercise as well. She really gets excited when I say the word "run". She knows what we are about to do.
So hopefully this helps you understand that staying fit doesn't mean that you have to have a set schedule and routine everyday. A change of pace is always good!
