Depends on your body type and metabolism and your routine. But usually it takes around 3 to 4 weeks for visible results. For me it took me a couple of months to actually see any progress visually.
A good rule of thumb is to use the 90 day mark (3 months) to test results. If youâre on a new workout and diet plan, focus on monitoring your results for 12 weeks to see how youâre doing. It takes this long to really see significant results with any type of solid nutrition and exercise program. If you donât notice changes in 90 days, switch things around.
