Been gymming at home with a couple of dumbbells and a pull up bar along with other body weight exercises. I used to gym consistently for about 2-3 months but since my exams were near I quit. I didnt see much results except my bicep vein was starting to show a bit other than that no significant results- didnt gain weight.

I am on a bulk- gain scene, but am also gaining some fat which is starting to show but I also want to bulk up and be muscular.

So I restarted today with the same workout program I used before- 3 days bicep and shoulder
-db curls 3 x 10 -pullups 20-30 reps -Db lateral raises 3x10 -db shoulder press 3x10

3 days chest back and triceps -pushups 3x15 normal, 3x10 narrow grip 3x10 decline (did either 100-150 pushups) -bench dips -3-6 x10

I have 2 5kg dumbbells, any advice?
