I've decided to focus on that exercise, hoping it will be sufficient to develop and maintain a level of fitness. My primary reason for choosing burpees is they require no equipment. Monday I did 10 sets of 5 and thought I'd die. Today I did sets of 5,6,7,8,5,6,7,8,5,6. Eventually I'd like to be able to do 10 sets of 10. Any suggestions? Should I focus on speed or correct form?
