Depending on the chosen split, strength training sessions last between 45 minutes and 2 hours. The fewer days you train, the more time you will need for a single session. To be on the safe side, you should allocate at least 60 minutes for strength training. Additionally, include a short cardio warm-up of about 10 minutes and a mobility warm-up of about 15 minutes. In total, you should plan for an average of 70 to 90 minutes for the training. Don't forget to account for the commute to and from the gym, as well as changing clothes and showering - you should also set aside time for these activities in your daily schedule.
