This is shocking.

New research has stated that healthy gut microbiomes is imperative for exercising because it can influence the persons overall health. A healthy microbiome can mean the person can obtain larger muscles.

“If antibiotic-treated mice had run less than untreated mice, then it would be more difficult to conclude a healthy gut microbiome was required for skeletal muscle to fully adapt to exercise, because it would more likely be the mice just ran less,” Prof. John McCarthy, Ph.D. said of the study.

“The muscle does not grow (hypertrophy) as much in a mouse with a disrupted gut microbiome as a result of antibiotic treatment, [compared with] a mouse with a healthy gut microbiome,” he added.
