The infamous Add 10 workout.
The structure is simple. Go straight through the exercises. Don't move to the next one until you've finished the reps for the one before.
Any time you stop, even for a brief pause, you have to add 10 reps to that exercise. So if you stop during Situps, add 10 reps (for a total of 160), and if you stop again, add 10 more (170 and so on).
Lot's of you have done this one before, so we're gonna challenge you to change up the exercises. If you have dumbbells, do Thrusters instead of Burpees for example. You can try Pike Pushups instead of Pushups, Lunges or KB Swings instead of Squats, etc. When you switch an exercises, swap it out for something that hits a similar body part.
Take your time. This one's a marathon.
100 Pushups (knees or toes)
(Intermediate - start with half the number of reps)
