Fitorex«No soreness means it was not a good workout»
False
What the evidence says
Soreness (DOMS) reflects novelty or muscle damage, not the quality of the stimulus or growth. You can make plenty of progress with barely any soreness, especially once you are adapted to an exercise. Measure progress by loads and reps, not by pain.
How settled this is
DOMS does not correlate well with hypertrophy.
