If you respond well to volume from a size standpoint, but have an extremely difficult time adding strength while doing it, you will SOON find yourself STUCK. How to get out? Well, you can try decreasing the volume and frequency some. This may work perfect, but many people grow fast on a relatively high volume routine, but the gains are just not sustainable because the trainees strength level rarely budges.
A good approach to solve this problem is to simply insert some LOW volume weeks into the mix. Many will find strength absolutely skyrockets with the volume and frequency so low. Add a chunk of strength to all your lifts for a short time, then jump back on the volume. I use this system quite a bit with training clients and when you get the volume to low volume ratios dialed results can be nothing short of fantastic.
