Strength preservation

Hi all,
Currently reverse dieting but I will have to do at least 2 more cuts as my BF is around 14-15%, and wanted to ask for your advice on the workout.

Day1:
Back and triceps (but no deadlifts as my forearms are too weak to do deadlift and row/chin ups)
Day2: kickbox
Day3: deadlifts then HIIT
Day4: kickbox
Day5: Chest and biceps
Day6: Legs and shoulders
Day7: rest

I usually do heavy compound sets with 4-6 reps and never train more than an hour. What do you think about the routine? Should I add more weights? My legs are actually getting bigger but my arms and shoulders have shown no progress in the last 4 months. Thanks
