Day 19 looks like Day 5 from across the room - burpees, 20 seconds on, 10 off, four intervals per set at your level's 3, 5 or 7 sets - but the drawing tells the real story: these burpees carry a push-up in the middle. Squat, kick back, chest to the floor, back in, stand. The clock stayed. The rep grew.
That single addition rewrites the day's economics. A basic burpee cycles in about two seconds flat; putting a full push-up at the bottom nearly doubles the work per rep and drags the chest, arms and shoulders into what used to be a legs-and-lungs affair. Fewer reps will fit in each window and that is expected - the program is trading rep count for rep cost, the same exchange it has been teaching since the intervals started growing.
Keep the push-up real inside the rep: plank first, chest all the way down, full press back up before the feet jump in - a nodding head over bending elbows does not count. Everything else follows Day 5's standards: flat hands, straight plank line, complete stand at the top. Rhythm over panic, always.
Two weeks ago this clock carried basic burpees - today every rep touches its chest to the floor, and that difference is the fortnight, measured.
Make it Harder: Jump the feet back into a tight, braced plank and snap them straight back in - no lazy kick-backs.
Make it Easier: Take one full breath at the top of every rep before dropping into the next.
