If you do wish to experiment with tribulus you can take 750-1250 mg per day divided between meals. Some people experience stomach upsets but this can be minimized by taking it with food. There's no guarantee that tribulus terrestris will help you grow bigger muscles but many users report a much improved sex drive!

Many bodybuilders concentrate primarily on their muscles' positive and static strength but equal focus should be given to negative strength, or lowering weight, if true muscle failure is to be achieved. You can emphasize this aspect of training by completing a set of negative reps after reaching positive failure.

You'll need one or two partners to lift weight to top position so that you can lower it under your own control. Once you can no longer control descent, set ends. Take special care with leg exercises and avoid negative squats to protect knees.

Beginners should not attempt negative reps while intermediate and advanced bodybuilders can be imaginative in how they incorporate negative reps into their training programs.
