Lower volume, higher frequency, and lower reps, higher weight are what's mostly endorsed around here for optimal training during a cut. If WS4SB allows for all these you're in good shape. Maintaining muscle is a good goal, but you shouldn't shoot to just maintain strength. There is no reason you can't improve your strength while cutting albeit a tad slower than with a hypercaloric diet.
Your diet is what will mostly determine your success, though. Morning walks are also good to clear the mind and jump start the day.
