Depending on your training split, strength training sessions take between 45 minutes and 2 hours. The fewer days you train, the more time a single session will need.
To be safe, plan for at least 60 minutes of strength training. In addition to that you will do a short cardio warm up of about 10 minutes and a mobility warm up routine of about 15 minutes.
Therefore you should plan for 70 to 90 minutes of total training time on average.
