Workout Update: Transition Day 2

For today's workout, I did one of the B4 Lift 4 workouts, specifically, the shoulders and arms workout. This is a very short, just 20 minutes, circuit workout in which you do three sets of a resistance exercise (shoulder presses, bicep curls, and triceps kickbacks), and in between each set, you do 30 seconds of HIIT cardio (burpee/squats, squat jumps, and wide plank runs/mountain climbers). So, basically, you do 10 reps of the resistance move, then 30 seconds of the cardio move, then 10 reps of the resistance move, then 30 seconds of the cardio move, and then 10 reps of the resistance move, and finish with 30 seconds of the cardio move. Each time, you rest less in between moves so on the final round of the circuit you do the resistance move and then immediately go into the cardio move. So, it definitely gets your heart rate up. The workout finishes with two different core-focused moves that you do back-to-back, for 30 seconds each move, again doing three rounds. There is one person in the group modifying by using bands and doing lower-impact versions of the cardio moves.  From looking at the workout calendar for Lift 4 it appears that some of the "regular" workouts follow this format while others do all the resistance moves first, then all the cardio after the resistance moves are finished. Tomorrow is day 1 with Beginner Pilates in the morning and then the Lift 4 chest and triceps workout in the evening.
