My immediate goal is fitness (fat loss, increased work capacity, etc) so the goal is a six workouts per week alternating between a circuit and a cardio workout. I'm going to swap my cardio workout for the tabata protocol.
The circuit routine is mostly body weight exercises... Pushups, squats, lunges, and dips. Back, shoulder, and bicep exercises are handled with resistance bands. Resistance bands provide way better workout than I expected, and are a hell of a lot cheaper than a gym membership.
So far I haven't hit my goal of six workouts per week yet. What happens is either I feel to physically drained and need to take a day off, or work / child rearing / keeping up with the house manages to get in the way. I usually get at least four workouts in per week, but I hate the cardio a lot, and it's usually the workout that gets skipped.
Tabata was a lot more challenging in a good way than a regular cardio routine, and since it takes a lot less time I can see myself finding more reasons why I can squeeze it into my day than finding some way to weasel out of spending 35 minutes doing something I'd rather not.
Last night for the Tabata all I did was run in place as hard as I could, but it was definitely a tough ass workout.
