Anyone do these sets and reps?

[holyjoy]

2 x 12 and 2 x 15 so four sets in total of one exercise?

If so would you know the theory behind it?

The number of reps doesn't really matter as long as you are reaching near failure in the last couple of reps

I don't know what they would be for. Lower is for strength, higher is for hypertrophy. But that's usually 8-12 for hypertrophy. That said there was someone at my gym the other day that was being told 15 by her PT. Don't know why though. Are they all at the same weight?

I don't know why 10 vs 12, but I have usually trained on a 5 by 5, 10 by 4, 3 by 15 basis, not always though. At PT, we start with the big compound exercises that require explosive power - pull ups say - and usually do 5 by 5 of them. "Finishers" - triceps and lats supersets say - might by 3 by 15 or even 20. Some harder moves may even just by 3 sets by 5, again done at the start of a session.

The crucial thing is - how heavy? 15 reps seems a lot, if you're lifting properly ie heavy and on a progressive overload programme.

My heaviest lift at the moment is 2 x 95kilo deadlift. Wen i pull a 100kg DL, I do one, and reset, or even take a 2 minute break between lifts.

Good point @tilestoclean but if you're doing 15 and only getting to failure on the lat 2, you're not lifting heavy enough! For strength growth, 5 or 6 on the big compund lifts should be enough. Maybe up to 8 or 12 on accessory lifts, like squat thrusters with dumbells.

No expert at all, but I follow the basic principle of 10 to 12 reps.

If I can do 12 reps without reaching failure, I increase the weight and start aiming for 8 reps. Lather rinse and repeat.

I dont go any higher than 12 on any of my sets and quite often its 8. Every set/workout is based on RPE (rate of perceived exhaustion) though. If i could do a set of 15 then my RPE would straight away tell me i had to increase the weight.
