The Claim
Incorporating a 20-second loaded stretch between resistance training sets enhances lower leg muscular adaptations and promotes soleus hypertrophy without increasing total workout duration, providing a time-efficient method for optimizing calf development within fixed training schedules.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you add a quick 20-second stretch with some weight between your sets of leg exercises, you might build bigger calf muscles without making your workout longer. This works because you're stretching during your normal rest time, so it's a quick way to get more out of your training.
See the scientific wording
Adding a 20-second loaded stretch between sets of resistance training enhances muscular adaptations in the lower legs without extending total workout duration, as the stretch is performed during the standard rest interval, making it a time-efficient strategy for individuals seeking to maximize calf muscle development within fixed training schedules while potentially improving soleus hypertrophy.
What the research says
1 studyStudy: Loaded inter-set stretch may selectively enhance muscular adaptations of the plantar flexors
Adding a 20-second stretch between sets of calf exercises can help grow the soleus muscle and improve strength without making your workout longer. However, it may not significantly increase the size of the other calf muscles.
