Plan A Realistic Beginner Strength Training Week

Walking into a gym with no plan means doing whatever machine is free and calling it training. This builds a proper weekly structure for a beginner: what to do each session, roughly how much, and how to know when to add weight. Suits anyone who has a gym membership and has been meaning to use it properly.

You are new to strength training and want a realistic weekly plan. You can train {DAYS_PER_WEEK} days a week and have access to [a standard gym with free weights and machines].

**Build a beginner strength training week:**
1. Assign a focus to each training day (for example, full body or upper/lower split) appropriate to the number of days
2. List four to six exercises per session with suggested starting sets and reps
3. Explain, in plain terms, how to know when to increase the weight
4. Flag the two most common beginner mistakes with this kind of plan
