A single dose of caffeine not only improves endurance performance, research also shows that the right dose will also boost short-term maximal exercise capacity such as weight lifting exercise.
British scientists showed that a caffeine dose, 5 milligrams per kilogram of bodyweight per day increased maximum anaerobic power output. This performance test involves a 30 second all out sprint on a calibrated stationary bike. However, the energy systems used in this test are similar to the ones used in intense resistance training.
The dose used in this study equates to 400 milligrams for a 180 pound person. However, I believe that a moderate dose of caffeine combined with compounds that potentate its effects such as green tea extract, will boost weight lifting performance more effectively.
Dymetadrine Xtreme is a research-based formulation that is designed to amplify the performance-enhancing effects of caffeine. Each serving contains a high dose of pure green tea extract that is shown in research to potentiate caffeine’s effect on the metabolism as well as a host of other co-factors. I’d recommend one serving of Dymetadrine Xtreme, at least 30 minutes before your workout.
