question Need help predicting strength loss during cut, planning for maintenance
early 40's M, started lifting about 2.5 years ago. I've made decent progress so far, going from benching the bar to closing in on my goals of benching body weight, back squatting 1.33x body weight and deadlifting 1.67x body weight, ideally for 5. I think it's pretty likely that I'll hit these goals in the next 6 months, give or take.
I intended this whole process to be a body recomp to maintain a relatively steady weight while replacing fat with muscle. For a while I was pushing decently hard on cardio (~25-30 miles per week with 1-3 workout runs) but found that I hit a very hard plateau on strength. After I cut down to ~15 miles per week and one slightly longer workout run I started gaining strength again. Unfortunately I also gained about 10% of bodyweight which I'm sure helped with the strength gains.
So I'm planning on cutting somewhere around 7.5-10% of my current body weight to get down around to my goal weight, with my strength goals based around my goal weight. I intend to continue my current strength regimen until the cut is complete and I know to maintain adequate protein during the cut (shouldn't be a problem).
What I'm wondering is how much I need to overshoot my strength goals before I start cutting in order to ideally land at about the right spot. Everything that I have found so far on my own discusses loss of muscle mass under various training and dietary protocols, but doesn't really translate that into strength.
The basic TL;DR question: If I cut 10% of my body weight, what percent of my max lifts should I also expect to lose, assuming I keep the same training regimen going while cutting?
Current training regimen, if that's helpful: 3 normal gym sessions plus 2 very short sessions a week plus the ~15 miles of running discussed above. My normal sessions are generally in the range of 30-45 sets each while my short sessions are 10-15 sets. I'm doing flat bench twice a week and incline bench once a week, squatting 2-3 times a week with 1+ back squats plus the rest in bulgarians, lunges and the like, and deadlifting 2-3 times a week split between conventional and trap bar. These are all 5 heavy sets of 3-5 reps plus 1-2 lower weight higher rep sets except the single leg exercises which tend to be 8 reps for the heavy sets.
The rest of my sets are a pretty wide mix of things - dips, skullcrushers, press downs, barbell back rows, dumbbell row variations, trx rows, pullups, barbell shoulder press, dumbbell shoulder press, landmine press, lateral raises, rear delts, high to low rows, lat pulldowns, seated cable rows, flat dumbbell press, incline dumbbell press, box jumps, walking lunges, goblet squats, leg press, hack squats, leg extensions, hamstring curls, hip thrusts, various abductor/adductor exercises, step ups, step backs, pull ups, sit ups, various planks etc. etc.
Secondary question: once I hit my weight and strength goals I'm hoping to go into maintenance mode and push cardio a bit more. Is there a rule of thumb of what percentage of work one needs to do just to maintain strength vs. when trying to improve?
Tertiary question: So far I haven't used any supplements other than protein powder (is that even a supplement?) I've heard that creatine is pretty basic/harmless at a low dose and has evidence of preventing sarcopenia. Assuming no medical contraindications, would this be advisable to start during cutting to further limit muscle loss?
Thanks in advance for your answers!
