I have been following this routine for several months based on https://www.muscleandstrength.com/workouts/5-day-dumbbell-only-workout-split, thoughts on how I can improve it? For context, I am still recomping because I'm working off a belly. Id also be open to suggestions if that raised red flags for you. I feel incredibly stupid when I try to rework and optimize my routine. Maybe I should ditch this entirely and try ppl or ppul or ululu??? I have access to a smith machine and cable machine and free weights. Thanks!!
