Remember to lift as heavy as you can with good form, don't do puny granny weights if you want to grow.

That was exactly 7 months ago. You should see me now. Lol just kidding. 4 exercises a day is not good enough imo. You can do so much more with dumbbells. I workout only with dumbbells, a bench, and a pullup bar when I don't go to the gym and it shows results all the same. Deadlifts and squats are usually my main compound movements for "warmup" before I start my workout.
