Try to pick a weight with the kettlebell that you can do unbroken. Keep moving and rest in between rounds, not reps or movements. Support your swings by maintaining a tight core and squeeze your butt at the top of the swings. Tallballs are just tallballs. Find a good breathing rhythm and power through them. On your burpees, try to land on your heels when you're getting off the ground. No ground humping. Stay tight even through your burpees.
