Starting a workout routine as a beginner is a fantastic step toward better health! Here's a simple routine to get you started. Remember to consult a doctor before beginning any new exercise program.

### Cardio:
1. **Walking or Jogging:** Start with 20-30 minutes, 3 times a week. Gradually increase the duration or intensity as you get comfortable.
2. **Cycling:** Use a stationary bike or ride outdoors for 20-30 minutes, alternating with walking or jogging days.

### Strength Training:
1. **Bodyweight Exercises:** Start with 2-3 sets of 8-12 repetitions.
- Push-Ups
- Bodyweight Squats
- Lunges
- Planks
- Glute Bridges

2. **Dumbbell Workouts:** If you have access to dumbbells:
- Bicep Curls
- Shoulder Presses
- Dumbbell Rows
- Goblet Squats

### Flexibility and Mobility:
1. **Stretching:** Stretch after workouts or on rest days to improve flexibility. Focus on major muscle groups like hamstrings, quads, chest, back, and shoulders.

### Tips:
- **Consistency is Key:** Aim for at least 3-4 days of exercise per week, gradually increasing as you get stronger.
- **Start Slowly:** Don’t push too hard in the beginning to avoid injury.
- **Rest and Recovery:** Allow your body time to recover between workouts. It's when your body rebuilds and gets stronger.

Consider working with a personal trainer or fitness instructor, especially in the beginning, to ensure you’re using proper form and techniques.

Lastly, listen to your body. If you feel pain beyond normal muscle soreness, it might be best to rest or consult a professional. Enjoy your workouts and celebrate your progress along the way!
