An fitness regimen for beginners usually consists of a combination of cardiovascular, strength, and flexibility activities. Begin with 20-30 minutes of cardiovascular activity (walking, jogging, cycling), then go on to strength training for the main muscle groups (squats, push-ups, lunges), and end with flexibility exercises like yoga or stretching. Try to get in at least 150 minutes a week of moderate-to-intense activity; as your fitness increases, progressively up the duration and intensity. For individualized guidance, speak with a healthcare provider or fitness expert.
