I just finished my 4th week of OSC. In the article it doesnt say anything about warmup sets. Two of the days start with jump rope and the inch worm and the other two days start with squat thrusts. After this it just goes straight into the weighted movements. Should I be doing warmup sets with lower weight on these movements first?
When I did OSC I would warm up by one or two light sets before to get used to that exercise.
The GPP portion at the beginning of each workout is sufficient for a warm-up. If you feel the need, feel free to perform 2 sets of 2-3 reps with a 10RM.
