High VS Low Reps for Abs: finally settling the debate!

Are high reps or low reps better for the abs

There is a huge argument as to whether low reps is better than high reps when it comes to training the abs. I have decided to put this argument to rest by telling you what is best for your abs and why.

What is high reps?

Before I get into the debate I want to outline some terms.

When we say high reps we are talking about a large number of repetitions done for a certain abs exercise such as the crunch or sit up. High usually refers to a number greater than 15 or 20 but can mean much higher in certain cases and certain exercises.

Here is the key: when people talk about high reps they usually mean that the exercise is done at a fast pace and with no added weight. This is the main problem and will be discussed more later.

What is low reps?

Low reps refers to any number below about 15 when we are talking about the abs. In other bodybuilding exercises like the bicep curls, bench press or squat low reps would refer to a number less than eight - usually six or five.

The BIG PROBLEM with this debate

I have a big problem with the whole high versus low reps debate. The reason people are saying different things and getting confused is that everyone is getting their terms and their methods confused.

For example, when someone says they only do a low number of reps for their abs this DOES NOT mean that they go to the gym and do five easy crunches with no added weight and then go home and watch their six pack grow! What it DOES mean is that they add weight to each exercise, do it slowly with perfect technique and FAIL after that amount of reps.

Fail is there key word here. It is the number (in weight lifting) where you are too sore or tired to do any more in that particular set. If you are telling people you are doing low reps for your abs but you aren’t failing when you finish then you are just kidding yourself - you aren’t training properly.

The same goes for high reps. People who train with a high number of reps CORRECTLY do not go out to the gym and pump out fifty crunches at lightning pace with bad technique. They just don’t. If you want to train high reps correctly you still use good technique and you still go to failure or near failure. Again - if you aren’t you are just kidding yourself.

So which is better? High reps or low reps?

Now we get to the big question everyone is waiting for - which is better for your abs, high reps or low reps?

As far as I am concerned there is only one good answer that any trainer worth his/her salt will tell you. Low reps with added weight and perfect technique is the best way to build strength, power and overall muscle development in your abs.

It is not rocket science either. When you look at the biology of a muscle and how it grows we see that when you weight train the muscle tears slightly. The muscle growth is when the tissue is rebuilding after that stress and hence the muscle gets bigger. If we want to increase the muscle size as fast as possible, which we do if we want to tone and make our abs visable, then we need to put them under a large amount of stress. This is done best by using a heavy weight which will, in turn, cause you to fail at a low number of reps. Simple.

Or is it? Some people may argue that the muscles are just as stressed after doing a high number of reps as they are after a low number! Interesting debate. I dont buy into it though! I have never seen a person make amazing gains using high reps. Never.

Jamal said:I agree with your assessment wholeheartedly. I used to use the high rep method, but saw little strength gains in my core section. After using a 35lb. plate, held behind my head, and doing 5 sets of decline sit ups, I saw drastic gains in strength.
tarun said:i think you need to reconsider because low rep builds power and strength, high rep builds muscle mass which doesnt necessarily mean strength. Think about it properly, if you lift really heavy weights and keep increasing weight not reps, your body will have to adapt to lifting heavy things. If you lift light things alot, you body will just build endurace towards lifting light things but wont get any stronger.
nicky said:what would be a good weight to put on your chest in order to do low reps with higher weight to get abs? i would like one that doesnt fall or slide off or dig into my chest because of my boobs.
Corey said:I agree. I have visible abs and almost always have. I do high reps for first set sometime just to get them slightly fatigued. Then add some weight and pump out no more than 10.
tbone said:What about drop sets(decreasing weight) do they build mass and strength?

rafe said:okay this is concerning the abdominals, but what about the entire core in general, lower back, obliques and abdominals, im not saying weighted low reps ent bad but isnt it fair to say that u shud work through the motions of working upto higher reps then slowly addindg weight and decreasing the number of reps till ur at about 8 reps for that specific exercise...?
christian said:looking fat is a good bussines.
George Rock said:I think Corey above has the right idea. Work your abs with weight and by no weight. I am gonnn try this. I got oneof those ab king pro machines and I am gonna use that and also do loaded weight ab crunches.
Kelly said:Concerning Tarun's comment, while you are partly correct as far as high reps build endurance, low rep, high resistance builds strength, you have to consider this...If you comapre two people, one who has been working out with low, rep and another with high rep and ask them to toss a 5lb plate as far as they can over and over until they are exhausted...the person who has been tossing 2 1/2 lbs 100 times a day and a person who was only tossing their 100lb plate 10, 5lbs is going to be like tossing a golf ball...and trust me, I can toss a golf ball more than 100 times. Overall fitness should be a concept focused on more so than endurace over strength. In order for your muscle to grow it needs to be forced beyond it's normal use to adapt.
Dave said:Are you endorsing the idea then of using 200 lbs of weight on an ab machine? Seems like someone is likely to strain a back muscle, a disk or get a hernia trying to do 10 or 20 of them. Would 100 reps at 120 lbs get good results without the risk of injury to other surrounding tissue?
David said:Weighted crunches shouldn't be done on any 'ab machine'. The strain on your body from being forced into an unnatural body position and a specific movement (everyone's different - size, shape, flexibility etc) will inevitably result in injuries. Also, through a combination of bad form (pulling/pushing with arms, or straining neck etc) and poor ab machine design, most people do not hit the abs as hard as they'd like to anyway.

In my opinion the best techniques for doing weighted crunches, in order of effectiveness (possibly descending degree of difficulty too so be careful!) are
1. on a swiss ball with hands behind head grasping a rope attachment on low pulley (keep weight low until mastered body position and balance)
2. on a swiss ball holding a (light) weight plate or medicine ball, arms stretched above head to start
3. on mat holding weight as mentioned above.
(add a twist to any for obliques)

Combining high rep (low resistance) and low rep (high resistance), be it in same workouts or separate (always at least 1 days rest between) has been the most effective method for me personally (hits more of the different types of muscle fibres).
So give the ab machines a miss, invest in a swiss ball (ask your gym to) and prepare for an ab pump you've never experienced before.
NB if you are doing crunches on a ball and don't feel it working your abs very well check your body position, your lower back should basically be as far back on the ball as possible without falling backwards (if taller use biggest ball).
Add in the swiss ball jack-knife (look it up) and get your body fat low enough to see your new 8 pack (i recommend extra high intensity interval training and/or martial artist or boxer style circuit training).
