1. goal: endurance and fitness.
If you want to build a good figure or improve muscle endurance by exercising muscles, the most appropriate way is to reduce the rest time as much as possible.
Most people retrain for fitness or weight loss, and they don't need big muscles. It is suggested that they train continuously and reduce the interval time of each group, which is often seen in training for about 30 s-60 s.
This can not only maintain the heart rate, but also replace the way of completely relaxing muscles with a very short rest, which can increase the weight of muscle load and burn more calories.
2. goal: strength and muscle
If you are trying to increase your strength, the principle that has been applied for many years still applies: your muscles need to get enough rest to fully recover.
Moderate rest can secrete hormones responsible for muscle repair and repair muscle tissue damaged by retraining.
Therefore, if you are re-training to strengthen your strength, the recommended rest time is about two to five minutes between groups.
A little advice: If you are a beginner or a novice, I suggest that you get enough rest and recover better physical strength, so that you can complete the target group number completely and are not easy to get hurt. Cultivate good self-confidence and be more active and lasting. Gradually adjust with the enhancement of physical fitness.
