Double progression decides if you add weight to everything.
For example…
If you use 200lbs for your work sets of 3-5 reps and then 180 for your EMOM sets and you do:
200lbs x 5
200lbs x 5
200lbs x 4
180 x 3 reps EMOM 4 minutes
Then you keep the same weight on everything at the next session.
If at the next session you do…
200lbs x 5
200lbs x 5
200lbs x 5
180 x 3 reps EMON 4 minutes
Then you can go up to 205 or 210lbs for the sets of 3-5 and 185-190 for the EMOM sets
