So about this Freeletics stuff...I think it's a pretty cool concept. The idea is basically that you have some set of exercises, which could be pretty small like this:
or pretty big like this:
and you just try to do the entire workout as fast as possible. So for the first one you would do 10 burpees, then 10 climbers, then 10 jumps, then 25 burpees, and so on, taking breaks whenever necessary but focusing on finishing the workout as fast as possible. Then the next time you do the same workout you try to beat your previous fastest time. And if the workouts get too easy, there are harder versions. For instance, the "strength" version for the second one is
I like it personally because
A: Most of these you don't have to go to the gym to do
B: You build strength and cardio at the same time
C: It's really efficient time-wise, since there's a built in incentive to get through the workout fast and beat your previous fastest time
I'm not in great shape so I'm typically sore for a couple days after a moderate-length one, and I only end up doing 2-3 workouts a week. This works well for me since I don't really have time to work out every day, lol.
With a free account (which is all I have right now) you can see like 5 different workouts, and the full version is priced at 40 euros (~$51) for 3 months (I'm not sure what all you get for this).
My times for the two workouts i've done:
50 burpees, 50 pullups, 100 pushups, 150 squats, 50 burpees - 39:55
50 burpees, 50 squats, 50 situps, 40 burpees, 40 squats, 40 situps, 30 burpees, 30 squats, 30 situps, 20 burpees, 20 squats, 20 situps, 10 burpees, 10 squats, 10 situps - 28:15
