The amount of rest you need between workout sets can vary based on your fitness goals, such as building muscle, increasing endurance, boosting strength, or losing weight. Rest needs may also be influenced by your age, weight, fitness level, and genetics.
Exercises geared towards building muscle involve overloading your muscles to create a temporary trauma to the muscle fibers. This causes the fibers to grow, increasing the overall size of the muscle.
Typically, you will do eight to 12 repetitions at 60-80% of your one rep maximum. Then, you will rest for about 30 to 90 seconds between each set to promote muscle growth.
Strength training is less about muscle size and more about the strength or power of your muscles. You need adequate rest between sets so you can maintain a high level of production during your workout and build the most strength. Typically, you will rest around two to five minutes between sets. The exact time will depend on your current fitness level, age, and genetics.
A higher endurance means you can perform repetitions of a particular exercise over a longer time period. Exercises to improve endurance often involve using lighter weights and doing a higher number of repetitions with shorter rest periods.
For instance, 30 seconds of rest between your intervals will help improve your muscle endurance. Programs like HIIT (high-intensity interval training) can also help improve your endurance.
Resistance training can also be used to manage your weight and change your body composition. However, you also need to focus on nutritious eating and creating a calorie deficit (eating fewer calories than you burn). The amount of rest you need will depend on whether your focus is on building strength or endurance.
HIIT training is also a great way to burn calories and lose weight, which means 30 to 90 second rests in between sets. If you are new to working out, consider starting with a longer rest period to prevent injury.
Resting between sets allows your muscles to recover, prevents fatigue, and wards off injuries. However, resting too long between sets can cause your muscles to cool down and can impact your results.
Conversely, if you do not rest between sets, there is nothing separating one set from another. This can make it difficult for your muscles to recover and make your workout less effective. Researchers suggest that multiple sets are far more effective than single sets for building strength.
Here are some tips for maximizing your rest time:
- Consider your exercise type and fitness goals when determining rest time
- Use a timer to keep your rest times consistent
- Catch your breath and allow your heart rate to slow down slightly
- Take a sip of water if you need it
- Walk, stretch, or move around rather than standing still
- Make sure you feel comfortably tired but not exhausted before your next set
- Focus on form and adjust your rest time if you cannot maintain proper form
- Take more rest time if you are a beginner
- Gauge your available workout capacity and adjust your rest times as needed
