Do rows help with pull-ups?
Bent-over dumbbell rows
This exercise works your upper back and bicep, two areas that will help to lift you up into a pullup.
Are rows harder than pull-ups?
The reason you find bodyweight rows a bit easier than pull ups is because a pull up involves 100% of your bodyweight (plus any added weight like i would use), whereas a bodyweight row usually has your legs at least touching the ground.
Can pull-ups get you a six pack?
No, pull-ups are not an ab-isolation exercise. When you are performing these, your whole body is working, beginning with the hands and ending with your calves. Nevertheless, it is recommended that during pull-ups you try isolating your core.
