my goals are too get stronger or at least maintain my muscle now while losing some fat, i expect that i should probably start doing middle weight more reps instead of heavy weight for like 10 reps, with my goals explained i have a question...if im doing an exercise like db curling, i may be able to squeeze out 10 reps at a certain weight but not feel a thing after, and do 10 with a lighter weight and feel the blood pumping and really feel it working...my best guess on this is that with the heavier weight im not really focusing on good form im just trying to get the db back up...so basically is it better to focus on perfect form at a reasonably lighter weight in every exercise that i do? i.e. bench press, arnold press, db rows, db curls and close grip bench press...
