Post a video so it will be easier to advice please

Try to be as relaxed as possible and not over push the ball forward causing muscle

The simplest thing I see is you push the ball right as you walk left...the ball has to go behind you. Try pushing the ball left and not over pushing it and don't push it up, let it fall towards the ground plus letting it swing freely from your shoulder

Thank you for the advice, I will try both recommended tips/practice drills next time I hit the lanes to practice. I've always had problems muscling my swing.

I agree with what sps300 said.  Watching the video, the footwork seems to be the biggest issue, which will screw up timing and can screw up the swing.  Here is what I would do:

1) Definitely use the 1 step swing drill that was already mentioned.  This will help you become more relaxed throughout all parts of the swing.  If you muscle the ball, it will hurt consistency.  I do this drill from time to time if I run into a slump or if I notice any issues with my swing being off.  It was one of the first things my driller/coach worked with me on 2 years ago and it definitely does help.

2) Practice with the footwork.  The thing I noticed is you have a huge drift left when going into the 1st/second steps.  I would practice walking straight.  I think the footwork issue is causing your swing to go behind the back, which is one of the reasons the swing is being thrown off.  If the footwork can be corrected, then that will help you with the swing/timing.

I actually started really watching the video I made over and over and noticed my first step goes to the right then I start walking left on 2nd step. At the end point at my slide I end up with no drift from my start point. What can that step to the right cause?

In your 5-Step approach, your first step should be straight ahead, with your second step (first step in a 4-step approach) should be in front of your left foot.  You also need to work on your timing,  Your ball seems to be in ahead of your feet.  You swing should be at sholder height when you start your slide.  Is your ball too light?  What weight is your ball?  You seem to be able to muscle it around very easily.
