5. Introduce supersets - this involves performing two exercises for same muscle group without a rest interval. This means you have to utilize different muscle fibers which stimulate greater growth.

6. Use partial reps - at point of failure you will not be able to complete full range of movement for a given exercise. Completing a partial rep that uses only a segment of lift will still work your muscles beyond point of failure. This technique is especially useful to advanced bodybuilders as it allows them to increase intensity without adding extra routines that could cause overtraining.

7. Use isometric contractions - this involves holding weight still at point of failure to stimulate a static contraction in muscle.

8. Employ forced reps - this involves completing one or more final reps after point of failure has been reached. You will need assistance of an experienced helper to attempt this.

Once you have added these techniques to your training regimen you'll know you've done your best to maximize muscle growth.

Clearly there is significant scientific backing for claims that HMB can speed up muscle growth, strength, endurance and fat loss. There are no known side effects when taken properly in amounts ranging from 3-5 grams each day. It should be taken before training or at bed time for best results.
