Do this full body shred dumbbell workout at home if you want to build muscle fast.
It's more effective if you use heavier weights but they shouldn't be so heavy that you can't perform the exercises properly. I used 10kg dumbbells.
Some may make excuses about lack of time or not having the motivation. Don't let that be you. Do the workout with energy no matter how you feel.
Enjoy the full body shred dumbbell workout at home.
