Depending on your goals, I'd probably consider a change in your program. If you are training a bodypart once per week, that's a pretty low frequency and even though it might seem standard and what you read in the mags. It's not in any way optimal. That said, you don't want to double your workouts because that then doubles the workload over a week. If you do 6 sets of squats, you'd start with 3 sets 2x per week and then go from there. You can't make a 100% jump although it might be very tolerable after acclimating over 4-8 weeks (there are a lot of people here that can vouch for that who've made incredible gains squatting 3x per week for 5x5).
Also, take more time between sets on the big exercises. 1 min is just no where near enough. This is strength/hypertrophy training which for a given individual, eating appropriately, and not training in purely ultralow reps, are directly related - I give those caveats because everyone seems to like to dispute this with nonsensical logic. If you want strength/hypertrophy and if you want to train for it correctly, you can't try to make it cross training or cardio intensive.
Intensity is a % of your 1RM not really a 'preceived effort' as it's been used in HIT and then the BBing culture. So 100% is really the most you can possibly do for a single rep. Meaning your best set of 5 might be in the 85% range or some such.
So maybe that helps a bit or gives you an idea. In all honesty, I'd spend a lot of time reading those linked topics and working through them in your spare time. You'll thank me for it.
