Effective reps, even though some would argue whether it’s accurate or not, is STILL the best equalizer of high vs low volume and a silencer to much of the overthinking and noise surrounding peoples training.
5 sets, leave ~3 in the tank each set, ~10 “effective reps”
3 sets, leave ~1-2 in the tank each set, ~10 “effective reps”
2 sets, to failure, ~10 effective reps per set
Yeah in practice you might hit a little higher or lower depending on your perception and how fatigue carries through the sets, but ultimately that is is the jist. The only questions after that is not program related it’s YOU related, and any YOU questions can fluctuate over time. What do I enjoy the most is always the most important to me.
I don’t like 5 sets because I have a tendancy to push a bit too hard and burn out to soon. 2 sets is generally too commital to me, it puts too much pressure on me to perform and I always worry about form breakdown and injury. 3 sets I can pick a weight I know I can handle, keep good technique, and take at least one set pretty close to failure (end set when I know I’ll fail the next rep or break good technique). That’s how I answer my own “YOU” questions right now.
But guess what? And here’s the crazy thing, despite what the internet will have you believe, you don’t have to pick an allegience. I’ve had small niggles that force me to leave a few more reps in the tank for a while so I go a bit higher volume and progress that way whilst getting more of that all important blood flow. I’ve also had periods where I feel I’m overreaching or not recovering fully from 3 sets of a certain exercise but am enjoying pushing it really hard, so I’ll go to 2 sets for a while - just for that exercise.
Many people will rotate through these different training styles throughout the year. And on this 3 second eccentric talk, it’s more stuff you can figure out yourself. I love that shit on leg curls and leg extensions, occasionally I might do it on triceps work. 90% of the other stuff I just worry about controlling the weight. Do you like it on other exercises too? Wonderful. Keep doing it. Add reps and weight over time. Get bigger, get stronger.
Follow a ready made program or learn to evolve based on goals and what your body tells you over time. A lot of the other stuff you read will just harm your consistancy. Get in there and do the work. There will always be time to experiment.
