Long Limbs? Do More Isolation Work
Longer-limbed bodybuilders and lifters often struggle to move heavier weights than their stumpy-limbed brethren. Why? Because they have a longer range of motion – a mechanical disadvantage. Being tall has its perks, but lifting weights is rarely one of them.
It comes down to having longer levers. Compared to alligator-armed lifters, the lever arm of long-limbed lifters is much further from the torso. The solution is to add in more isolation work.

Add in some overhead extensions for triceps:
Now, this doesn't mean you should neglect the compound exercises like dips and chin-ups, but if you have long arms, don't forget the isolation work.
