The 100-Calorie Finisher #03

Hop on the rower, start a running clock and perform a 30-sec all-out row, aiming for max calories. Then, at the 30-sec mark, jump off and do 12 alternating lunges (weighted or body-weight ones), before strapping back in. Begin rowing at the 1-min mark with another 30-sec sprint, followed by 12 lunges. Repeat, rowing at the top of each minute until you reach 100 cals.
