Hoosegow is right. Now, if you want to get a "burn", and/or a "pump", try something with some lighter weights. You will get a burn, but probably not the maximum effectiveness of heavier weights to near limit. A ot of bodybuilders use a system similar to this to "pump" up before a contest. Take about a 60 % weight, do 5 full reps, then do 5 reps from full down to halfway up, then do 5 reps from halfway up to full up, then finish with 5 full reps. Many spinoffs on this. 21's are 7 full, 7 down to half up, the 7 half up to all up. Ladders are 1 full, then 1 from down to 1/2 up, then 1 from half up to full up, then 2 with all 3, then , then e and so on. 4,5, 6,7's are in the same manner, 4 full, 5 all down to 1/2 up, then 6 from 1/2 up to full, then 7 full. While you will feel a burn and get a pump, they won't really increase overall strength, but may help with work capacity. Also, the jury is still out on this one, but some exercise physiologists are linking the "burn" with increased gh release, but are not sure if the "burn" triggers gh release, or if gh release causes the "burn.
