if you want to grow your Twigs into thick defined arms you've come to the right place after cutting out all the fluff and focusing on just two SS backed exercises my arms grew bigger and Fuller than they ever have but don't just take my word for it I asked the top natural bodybuilders and muscle growth researchers the same question if you could only pick one biceps exercise and one triceps exercise what would you pick and they all pointed to the same two weird exercise is I've been using so like most people I started in the
gym with just standard bicep curls and I'm not going to lie they did the job but after I passed my newbie gains phase my arms became a lot harder to grow and that's when I started learning more about the potential downsides of regular curls they challenge your biceps mostly in the middle position when your arm is flexed but this is a similar type of challenge your biceps already get from back exercises like rows and pull-ups which also tend to be most difficult when your arm is in that same position plus because the biceps cross all
the way over the shoulder exercises like dumbbell curls don't stretch your biceps as much as they could be by exercises where your arms stay behind you which at least based on research for other muscle groups seems to be a powerful way to stimulate more growth but to discover the best exercise for your biceps scientists from a brand new 2025 study ran an exercise comparison they split participants into two groups one group did only incline curls for 8 weeks whereas the other group did preacher curls now although both these exercises work the biceps the challenge the
place on them is actually very different during incline curls your arms hang behind your body providing an even greater stretch on the biceps but the exercise is still hardest right around the middle just like regular curls with preacher curls however your arm is placed in front of your body so the biceps aren't stretched as much but unlike the incline curls this this setup now challenges your biceps much more at the bottom position when your arm is almost fully extended so with the study of design the researches wanted to find out what causes more growth an
exercise that focuses more on stretching the biceps or an exercise that focuses more on challenging the biceps than most at the bottom when the bicep is still quite stretched but just not stretched quite as much as it is during incline curls and the results were confusing incline curls led to more growth in the upper part of the arm but preacher curls led to more growth in the lower part of the arm another study that's yet to be released tested the exact same thing but using MRI for more accurate measurement and they got similar results so
what does this mean well theoretically to maximize growth in all parts of your biceps you'd want an exercise where the challenge is hardest at the bottom just like they are with preacher curls but without the arm held in front of the body so the biceps are more stretched which leads me to the weird exercise most of the fitness experts I spoke to recommended starting with Pro natural bodybuilder and Elite coach Alberto Nunes so for me personally uh I really like uh those pre-ra curl uh benches or tables that are really wide where I can lean
back and have my humorous in slight it's not full uh shoulder extension but they're right at about my midline and and basically perform a curl like this Daniel plin one of the science advisers for S with science has designed and published several muscle growth studies and explains why this exercise is so effective I'm going to have to go with a reverse creature curl it covers a lot of bases that wouldn't be covered with those compound back movements where the exercises are typically hardest in the mid to shorten position so by lying back on a preure
curl bench your biceps are still challenged near the bottom just like they would be during a normal pre-ra curl but your arms are positioned in more of a stretch because they aren't held in front of the body plus it comes with another unique benefit that most dumbbell curls miss out on and I found it very beneficial to just have something on my arm when I'm curling I really like the stability aspect of it when you think about it like you know arms like they can move all over the place that's something people forget is like
the bigger you get probably the more strict form you need because it's very easy for you to use your own body weight to contaminate an exercise however Dr Mike PhD researcher and competitive bodybuilder actually recommended an even weirder exercise that still applies a similar concept flat bench dumbbell curl really puts that tension at the maximum stretch and length and position of the muscles it has that same feel for your biceps that stiff-legged deadlifts done properly have for your hamstrings you know what I'm talking about like they're getting pull apart with maximum tension at the stretch
there's just no replacement for that once you try it it's like the crystal of champagne of bicep exercises you're like all the rest of this now I will admit this is quite the weird looking exercise and even I was skeptical at first now even though pumps and soreness aren't everything I'm not going to lie after I tried this exercise for the first time it gave me the biggest pump and post-workout soreness I have ever had holy that's insane so much so that it's easily become one of my current favorites but the downside of this version
is that they do lack the stability that the preacher bench provides and supporting your arms in this freeheld position can place a lot of Demand on your front delts so an easy fix I've been recommended by biomechanics expert coach is to position yourself sideways so that your arms are Now supported by the bench you might lose a bit of the stretch on the biceps but it does make up for it with the extra stability which I personally find makes this exercise a lot more comfortable but use caution both of these still require a good amount
of shoulder mobility and they will take some time to get used to so don't force it if if it feels off and start light I can do regular curls with 55 lb but for these I'm using Max 30 lb but because not everyone will have a preacher curl bench or feel comfortable doing the lion Dumbo curls there's a third option with cables now I have showed this in past videos but you set up the cables to about wrist height and then curl with your arms held behind your body while these do lack the arm support
you get from using the bench you still take the boxes in terms of the stretch and the resistance challenge now all three exercises are very similar in terms of what they're doing to the biceps so pick the one that best suits what equipment you have available but also feels really good on your joints like even with the best bicep exercise they only contribute to about 1/3 of your arm size the other 2/3 triceps and unfortunately most people use exercises that don't allow this muscle to reach their full potential like push Downs close grip presses or
dips but these exercises seem to mostly work just two parts of the triceps the lateral head and medial head which are what beef up the triceps from the front and side but the third head the long head is actually the biggest part of the triceps and beefs them up from the back and hangs down when you flex your arms so what's the better exercise to grow all three of these areas luckily scientist from a 2022 paper designed an experiment to find the answer for 12 weeks they had Subs perform overhead extensions with one arm and
push push Downs with the other arm now because the long head crosses over the shoulders whenever you do a triceps exercise with your arm overhead this muscle gets stretch which as you know by now in certain muscles seems to boost growth but surprisingly all three heads grew more with the overhead extensions resulting in 1.4 times overall triceps growth and the push Downs now we don't yet know why exactly the other two heads grew more and we could definitely use another study to confirm these findings but the researchers used MRI which is the gold standard of
measurement so the study is strong and this is also why every single expert I spoke to chose the overhead extension as their number one triceps exercise for triceps personally I just like the overhead tricep extension with a rope um very easy for me I would say Easy Bar standing or seated behind the neck uh tricep extensions are amazing if you're already doing pressing for your chest you're doing the motion for your triceps that has the other angles built in anyway might as well go overhead to get all those awesome benefits if I had to choose
one I'd go with an overhead tricep extension with a cable usually with my hand wrapped through the dandle and my elbow propped up it's one of the few exercises that feels really good on my elbow especially in that overhead position and it checks a lot of boxes so hardest in the lengthen position puts the long head the tricep in a lengthen position so can't go wrong but what you may have noticed is that each expert I spoke to Preferred a different Vari variation why I think this is where most people find their elbow issues over
time very few people after the age of 30 do you see like skull crushing like the 45 we know we've all done that but and when you see a young man doing it you're like okay you probably got five more years of that then you're going to be joining me over here in the cables so especially with tricep is like pick the movement that you just feel like it's it's just custom made for you so even though Dr Mike loves the bar overhead extensions my body structure finds it extremely uncomfortable because it locks my hands
into a fixed position I've actually injured myself a couple times trying to force it my personal favorite right now is either Daniel's single arm recommendation with cables because it feels easy on my joints or even something as simple as a standing single arm dumbbell overhead extension because it's just really easy to set up and doesn't rely on a cable machine being available but try out the different variations and what you're looking for is the one where you feel very little to no pain in your elbows or shoulders as you do it yet feel a great
pump in your triceps after you finish your set But whichever variation you do end up choosing here's the key if you're using cables bump up the cable to about hip height and stand close to the cable so that the challenge as hard as closer to the bottom when the muscle is stretched for the dumbbell version keep your upper arm lock straight up and down don't allow it to bend too much as you get tired and on all the variations don't stop halfway get his deepest stretch in the tricep as possible by letting your hand come
down behind your neck as far as it can but now the important part how do you actually Implement these exercises into your routine well first off it's not like all other arm exercises are useless but these are likely going to give you the most bang for your buck so make sure they're somewhere in your current routine by doing them for three sets of 10 to 15 reps at least one to two times per week and the good news is that with my new app built with science plus all of this programming is taken care of
