For beginners in bodybuilding, it's crucial to start with a routine that focuses on foundational strength, proper form, and gradual progression. Here's a basic beginner's routine that covers major muscle groups:

1. **Full-Body Workouts (3 times a week)**:
- Day 1: Squats, Bench Press, Bent-Over Rows, Overhead Press, Planks
- Day 2: Deadlifts, Pull-Ups (or Assisted Pull-Ups), Lunges, Dumbbell Shoulder Press, Leg Raises
- Day 3: Rest or Active Recovery (Light cardio, stretching)

2. **Sets and Reps**:
- Aim for 3 sets of each exercise.
- Start with a weight that allows you to perform 8-12 reps with proper form. As you get stronger, gradually increase the weight.

3. **Rest**:
- Rest for 60-90 seconds between sets to recover adequately.

4. **Progression**:
- Once you can comfortably perform 12 reps with a particular weight, increase the weight slightly for the next workout.

5. **Form and Technique**:
- Focus on learning proper form and technique for each exercise to prevent injury and maximize effectiveness.

6. **Cardio**:
- Incorporate 2-3 days of moderate-intensity cardio for overall fitness (optional but beneficial).

7. **Nutrition and Recovery**:
- Ensure you're eating enough protein and overall calories to support muscle growth and recovery.
- Get adequate sleep as it's crucial for muscle repair and growth.

Always start with a warm-up to prepare your muscles and joints for the workout. It's also advisable to consult with a fitness professional or a trainer when starting to ensure you're performing exercises correctly and to tailor the routine to your specific needs and goals. As you progress, you can modify and advance your routine to suit your evolving strength and fitness level.
