s s asked:


if you don’t feel aches after doing a dumbbell workout, does that mean your workout is ineffective? does taking short rest make a workout more effective than one without rest (the rest is in alternating arms). cos i feel aches after doing workouts without rest when compared to when i take some rest because of other stuff like checking handphone messages for a few min.
