Quick and not at all easy, descending prime number ladder of burpees & squats:

23 burpees, 19 squats,  17 burpees, 13 squats, 11 burpees, 7 squats,  3 burpees, 1 squat

Weight the squats if you’re able, with 1 or 2 dumbbells, or by starting with an empty barbell and loading weight with each set.

Then for the day’s energizer, drink 5 glasses of water throughout the day.
