When it comes to long workouts or intense training sessions lasting 90 minutes or more, having the right pre-workout strategy can make all the difference. The Endurance Pre-Workout Stack is designed to help athletes push through fatigue, maintain performance, and recover quickly, whether you’re running, cycling, or preparing for competition.
The stack combines four key supplements, each serving a specific purpose to maximize energy, endurance, and recovery.
Fast-Up provides quick, clean energy and mental focus. Taken 15 to 30 minutes before your workout, it delivers a healthy boost without the jitters or crash associated with typical energy drinks. Its blend of NADH, Coenzyme Q10, citrulline malate, and B vitamins supports cellular energy production, reduces fatigue, and enhances focus. For those who prefer a caffeine-free option, Up-Lift offers smooth, stimulant-free focus.
Glutamine Select helps with hydration, endurance, and muscle recovery. Mix two scoops in water, consuming half before and half during your workout. Its combination of L-glutamine and BCAAs reduces muscle soreness, speeds recovery, and helps preserve lean muscle. This supplement is particularly useful for athletes engaged in high-intensity or prolonged training and for those on calorie-restricted diets looking to maintain muscle mass while managing cravings.
Energy Reserve is designed to boost stamina and protect muscle energy. Taken 30 to 60 minutes before workouts with a carbohydrate-containing meal, its pharmaceutical-grade carnitine supports fat-burning while sparing glycogen, preventing early fatigue during exercise. It is especially beneficial for athletes on calorie-restricted diets or those preparing for physique contests. For optimal results, take additional doses with meals to gradually build carnitine levels in muscle tissue.
U40 Liver Tabs support strength, stamina, endurance, and muscle fullness. Taking six or more tabs daily promotes red blood cell health and faster oxygen delivery to muscles. Made from 100 percent Argentine beef liver, U40 provides heme iron and natural growth factors that enhance stamina, recovery, and muscle tone. Athletes often combine U40 with Mass Amino Acids and a quality protein powder for the most noticeable results.
Using the Endurance Pre-Workout Stack is straightforward. Take Fast-Up or Up-Lift before your workout, Glutamine Select before and during exercise, Energy Reserve before cardio, and U40 Liver Tabs throughout the day. Together, these supplements help you train harder, recover faster, and perform at your best in every session.
Whether you are preparing for competition, aiming to break personal records, or simply looking to get the most out of your workouts, this stack provides the tools to sustain energy, protect muscles, and support overall performance.
