If you are taking a month off from training, and you were to engage in high intensity cardio at the same time, you can kiss good bye to most of your muscles. I can assure you that your lifts after that particular month would be rock bottom. Good luck.

You should not stop working out or lighten the weight, you should continue doing what you would normally do in the weight room and ADD cardio as an ADDITIONAL routine. Never should you substitute weight with cardio completely.
Good points bro. You took the words right outta my mouth. Stopping weight training to focus purely on cardio is a waste of time.
Muscle atrophy occurs within 3 weeks, and we're not just taking that into consideration. Your lifts will go down also because of decreased neural efficiency. You see, each lift; bench press, squat, shoulder press, etc is a skill and basically by doing these lifts on a regular basis, your CNS has adapts to the movement.
So if you stop for a whole month, basically you have to start from lower poundages to rewire your central nervous system again (despite the advantage of muscle memory, it's still a waste of time).
