I recently started the Fierce 5 full body dumbbell plan after doing a homemade bro split routine, only problem is my limit to weight at home. For example, I do DB press for my chest but the weight isn't nearly enough anymore for 3x8. It feels like one exercise for each body part isnt enough. Could I keep the same program going, but add 1-2 sets to eat exercise to keep my progression going? I initially wanted to replace the workout with something more difficult, like flys, but that would probably ruin the program.
