Results With High-Volume Weight Training

Resistance training will help build muscle when you consume adequate amounts of protein and allow enough time for recovery. Weight training can also impact your body in other ways. Consider the findings of a study on lab rats published in the International Journal of Sports Medicine.
 
Matrix metalloproteinases (MMP) play important roles in the growth and remodeling of  different tissues. To see how they react to 8 weeks of resistance training, researchers tied weights to the tails of lab rats and had them perform 2 sets of 4 or 8 ladder climbs using 50% to 100% of their maximum carrying capacity.
 
The rodents that did 8 ladder climbs showed greater MMP activity compared to rats that did 4 ladder climbs and a control group that didn’t exercise. Higher volume resistance training increased MMP activity in muscle while reducing MMP activity in body fat.
