Afternoon Dr. Feigenbaum and Baraki
I understand that excessive cardio can affect a strength. I also understand that cardio is important to most programming at least to some degree. My question is when it comes to long term overall strength goals will cardio stall out that goal or will you eventually reach your goal it just may take more time? The reason I ask is because I like cardio. I do it on most my days off and sometimes multiple times a day. The difference with my cardio and resistance workouts are the resistance workouts (BBM programs) are designed around specific training goals and cardio i just do to stay very active and healthy if that makes sense. I usually do around 4-6 cardio sessions a week lasting 30-45 minutes. Nothing special with cardio usually around an RPE 6-7. On a side note I’m not looking to become a competitive power lifter. With the few months of proper training I have I think its reasonable to say over the next 2-3 years id like to bench 250-275, squat 350 and DL 405 all for reps.
Current numbers from where I started in February to now:
I’m 32 Years old 5’6 143# (FYI lost weight from 175 from last July to January)
Bench - 185 to 220
Squat - 175 to 265
DL - 205 to 280
It’s unlikely that you will be the strongest version of yourself if you’re doing that much cardio, but since you’re not going to become a competitive powerlifter- carry on 
I think you’ll meet your goals in the next few years too.

If you had to put a percentage of strength I would be missing out on what do you think it would be? I know it’s not an easy or one simple answer but are we talking 50 percent or 10-20? The Odds are my cardio will decrease once I work into a 4 day lifting routine.
One a side note, Are there any studies or information comparing running vs walking and its affect on strength? For example if I were to walk and burn 500 calories and run and burn the same amount of calories whats the difference if any it comes to affecting resistance training? Basically what I’m asking is it better to walk for my extra cardio/physical activity vs run when it comes to minimizing the affect on strength? I Apologize for the loaded questions haha.
I don’t know how much additional conditioning work will affect strength outcomes, as this is highly variable across individuals.
It depends what you want to do to determine “better”. Walking is lower intensity and has specific cardiorespiratory adaptations it elicits compared to running at higher-intensity. It’s a trade-off. What’s better? That depends.
If you want to minimize the interference effect, then you should slowly ramp up conditioning volume to the appropriate level (2-4x/wk depending on intensity, goals, etc.).
