- The lunges are R+L=2. You're welcome.
- Lunge twist: A regular walking lunge holding a dumbbell at your waist. Step forward into the lunge with your right leg and twist to the right at the bottom of the lunge, then repeat on the left side.
- Stab Crunches: Be sure to get fully extended back on each rep. Interlock your fingers behind your head (keep elbows back please). Flex your trunk as far forward as flexibility will allow.
- Thanks Shmoop for another stellar workout!
