What is the most suitable exercise time for muscle building

The most suitable exercise time for muscle building is generally between 30-90 minutes, and the actual duration is influenced by factors such as training intensity, exercise type, personal physical fitness level, recovery ability, and nutritional supplementation.

1. Training Intensity

High intensity strength training typically requires a shorter duration, 30-60 minutes, which is sufficient to stimulate muscle growth. Excessive extension of training time may lead to an increase in cortisol levels, which in turn inhibits muscle synthesis. When using compound movements such as squats and hard pulls, it is recommended to control the rest time between groups to avoid excessive overall training time.

2. Exercise type

Strength training aimed at muscle hypertrophy is recommended to be controlled for 45-75 minutes, including 6-8 movements. If aerobic exercise is used as a muscle building aid, the duration of a single session should not exceed 30 minutes. Hybrid modes such as cyclic training can be appropriately extended to 60-90 minutes, but attention should be paid to monitoring fatigue levels.

3. Physical fitness level

Beginners are advised to gradually adapt from 30-45 minutes to avoid overtraining. Intermediate trainers can extend it to 60 minutes, while advanced athletes can reach 90 minutes outside of the season. The difference in physical fitness directly affects the ability to withstand training capacity and needs to be dynamically adjusted according to individual recovery situations.

4. Resilience

People with sufficient sleep quality and nutrient intake can withstand longer training periods. When the training frequency is high, the duration of a single session should be correspondingly shortened. When experiencing persistent muscle soreness or decreased strength, it is necessary to reduce training time by 10-20 minutes.

5. Nutritional supplementation

supplementing carbohydrates 1-2 hours before training can support more sustained training. Supplementing branched chain amino acids during training can help prolong effective training time. Supplementing protein within 30 minutes after training is crucial for muscle repair, and this time window does not affect the choice of training duration.

Muscle building training should focus on training quality rather than simply pursuing duration, ensuring that each set of movements achieves effective stimulation. Warm up and stretch thoroughly before and after training to avoid sports injuries. Maintain a regular schedule and balanced diet, with a protein intake of 1.6-2.2 grams per kilogram of body weight. Regularly adjust training plans to avoid platform periods. It is recommended to use training logs to record the duration and feelings, and find the most suitable training time for individuals. Overtraining can have the opposite effect. When there is sustained fatigue or decreased athletic performance, it is important to reduce training time or schedule rest days in a timely manner.
