Strength training can not only shape the body, but also improve bone health, enhance muscle and connective tissue function, and improve blood sugar and blood lipid levels. Reasonable arrangement of training muscle groups is the key to improving training efficiency, promoting recovery and avoiding overtraining. This article will systematically introduce the classification, best matching scheme and training arrangement of different muscle groups to help you scientifically formulate a weekly strength training plan.
1. Analysis of the main muscle groups of the human body
Human muscles are divided into three categories:
- Cardiac: Heart muscle, responsible for maintaining life activities.
- Smooth muscle: Controls involuntary activities such as vasoconstriction.
- Skeletal muscle: Can be controlled autonomously, accounting for about 40% of body weight, and is the main target of strength training.
Skeletal muscles are further divided into the following major muscle groups:
- Chest
- Back
- Arms (including biceps, triceps and forearms)
- Abdomen
- Legs (calves, biceps femoris, quadriceps and buttocks)
- Shoulders (anterior deltoids, middle deltoids and posterior deltoids)
Each major muscle group also contains more subdivided muscles, such as the trapezius, rhomboids and latissimus dorsi in the back.
2. The difference between compound and isolated movements
- Compound movements (multi-joint movements): Exercise multiple muscle groups at the same time, such as squats, bench presses, deadlifts and shoulder presses. This type of movement is efficient and suitable for comprehensive strength development.
- Isolated movements (single-joint movements): Target specific muscles, such as biceps curls, although they mainly exercise a single muscle, they still require other muscles to assist in stability.
Research shows that compound and isolated movements each have their own advantages, and using them together is more conducive to the comprehensive development of strength and muscle.
3. How to match training muscle groups
Muscle recovery is the core of training plan. Muscles usually need about 48 hours to recover. Depending on the number of training sessions per week, the matching of muscle groups is different:
- Train twice a week
Full-body training is recommended, with compound movements preferred, covering all major muscle groups. Aerobic exercise such as walking, jogging or cycling can be arranged between training to promote cardiopulmonary health. - Train three to four times a week
“Workout Split” can be used to combine adjacent or related muscle groups to make full use of training time and ensure recovery.
4. Muscle group matching examples
Beginner plan (6 major muscle groups)
- Day 1: Chest + Shoulders
- Day 2: Legs
- Day 3: Back + Abs + Arms
- Day 4: Rest
Advanced plan (subdivided muscle groups)
- Day 1: Chest + Shoulders + Triceps + Forearms
- Day 2: Calf + Biceps Femoris + Quadriceps Femoris + Buttocks
- Day 3: Biceps + Back + Abs + Trapezius + Latissimus Dorsi
- Day 4: Rest
5. Weekly training plan demonstration
| Week | Training content | Recommended action examples |
|---|---|---|
| Monday | Arms and shoulders | Push-ups, biceps curls, shoulder presses, bench presses, lateral raises |
| Wednesday | Legs | Barbell squats, dumbbell lunges, Romanian deadlifts, step-ups, calf raises |
| Friday | Back, chest and abdomen | Dumbbell bench presses, dumbbell flyes, bicycle crunches, single-arm dumbbell rowing, supine crunches |
6. Various training forms
Strength training can be done in a variety of forms, including:
- Elastic band training
- Medical ball training
- Bodyweight training
- Free weight training (dumbbells, barbells)
- Training equipment training
All forms are good for health, and the choice should be based on personal goals, preferences and available equipment. For free weight training, it is recommended to choose a moderate weight that can be completed 8 to 12 times, and gradually increase the weight and reduce the number of times as strength increases.
7. When to seek professional guidance
Although there is a high degree of freedom in making your own training plan, a professional personal trainer can help you:
- Tailor your training plan
- Correct your posture to avoid injury
- Maintain your training motivation and continuity
- Arrange your training intensity reasonably to suit your personal fitness level
There is no single correct solution for strength training, but a reasonable combination of muscle groups and a scientific arrangement of training frequency and content can maximize the training effect. Whether you are a beginner or an experienced fitness enthusiast, combining compound movements with isolated movements, giving your muscles enough time to recover, and persevering can help you build a healthy and strong body.
