Ive been working out my whole body 3 times a week. I raise the weight with the dumbells and aswell as on the machines weekly or monthly. My chest hasnt been making any progress. Whats a good routine my friends were saying to switch it up like oneday triceps and bench like incline decline and flat. But will this be better then working out your whole body 3 times a week for about 1 hour and 30 minutes?
