Rep schemes remain in the hypertrophy range this week, but overall volume increases by adding more sets to individual exercises: up to five sets per move for larger bodyparts, and even 10 sets of calf raises on Thursday. This bump in volume will ensure that your muscles are overloaded sufficiently to continue the growth they’ve already begun experiencing in the first three weeks. Completion of this four-week program now entitles you to go to the next stage.
I now know that was a mistake. An eight-week Australian study that found that doing one of four sets of bench presses to failure produced double the strength gains compared to lifters who didn't take any of their sets to failure. But in a follow-up study, the researchers found that doing more than one set to failure on the bench offered no additional strength gains.
Pros: This technique not only allows you to do more work in a shorter period of time but it also creates an incredible pump (especially when you pair antagonistic exercises), and it helps burn fat by elevating the heart rate to the fat burning zone (which also improves your cardiovascular conditioning). Finally, you can use this technique all the time.
Arnold sought out alternative exercises that worked a target muscle from slightly different angles. When using dumbbells rather than the barbell on overhead presses, for example, he deliberately lowered the weights several inches below the bottom position of the barbell movement, and he brought them together at the top to elongate the range of motion.
For every person who lifts weights these days, it seems there are two who have a podcast about it. There are more bodybuilding tips promising greater strength and muscle than ever before, and along with them a ton of confusion; one buffed-up Instagrammer says lifting heavy will get you swole, while a well-known fitness personality has claimed in recent years that two 30-minute workouts per week netted him 34 pounds of muscle in a month.
