Question about lessening my training days

[khajihana]

Hi! I train 3 times a week now, and want to know if I can maintain my current physique if I go down to 2x weekly. (This, because I also do BJJ 5 hours a week with full time Job & partner) My schedule is Pistol squats, weighted pushups, hollow body crunches, chin ups, inverted rows and weighted dips. Everything 3 sets, 8-12 reps. If I go down to 2, weekly, will my physique/strength stay the same? Or will it declinatie? Thanks!
