The cable variation of the dumbbell front raise allows you to keep more tension on the anterior or front delt. With the handle slightly behind you, you can also achieve a more effective range of motion. It also keeps your form tighter.
To avoid twisting, keep one leg forward, one leg back. The leg in front should be opposite to the working arm. (The body works athletically in an "X" – the right arm for example works with the left leg.)
It's easy to change the muscle recruitment for new stimulation. Just alter your stance and bring the working arm more out to the side or across the body. You're still hitting the front delts, just in a slightly new way.
For this intensity technique, do the concentric part of the exercise on your own, then have your training partner push down during the negative as you resist.
If you've been around weight training for any length of time, you've probably read or tried an arm specialization routine. There are a bunch of these around with different cool names for what amounts to the same old shit: do a bunch of arm exercises. Yeah, the exercises change and the sets and reps change, but it still amounts to just doing more arm work.
