I've been focused on building my forearms lately and can't decide between hammer curls and reverse curls. Hammer curls feel like they really work the brachialis and brachioradialis, but reverse curls definitely hit the forearm extensors harder. Should I be doing both? Or is one better for hypertrophy? Curious what others think!

  I usually do a full forearm day every couple of weeks. I mix hammer curls, reverse curls, and wrist curls. It's a great way to really focus on hypertrophy!

  I'm not sold on the idea that one is 'better' than the other for hypertrophy. I've tried both, and I didn't see a huge difference in my gains. Maybe focus on getting strong at both instead of chasing some elusive 'better' option.

    If you're expecting the perfect forearms from just two exercises, good luck! Life is more than just hammer and reverse curls. Get outside and do some real lifting

    It's also worth mentioning the role of nutrition in recovery and muscle growth. Make sure you're getting enough protein to support muscle repair after those intense arm sessions. Aim for at least 1.6g/kg if you're serious about growth.

  Why not just do both? Life's too short to limit yourself to one boring movement. i just pick whatever I feel like on that day, which is usually whatever exercise I hate the least.

    I think incorporating both in different phases of your training could be beneficial. Maybe focus on one for a few weeks, then switch it up. That way you can see which feels more effective for you.

  I would suggest incorporating both hammer curls and reverse curls into your routine. Hammer curls are great for overall arm development, while reverse curls really emphasize the forearm extensors. A balanced approach can help you achieve better hypertrophy

    When it comes to hypertrophy, both hammer and reverse curls serve distinct purposes. Hammer curls predominantly work the brachialis, which can help increase arm size overall. Reverse curls, on the other hand, target the forearm extensors, contributing to grip strength and forearm aesthetics. Incorporating both allows for comprehensive arm development. Just be sure to monitor volume and intensity to avoid overtraining. Tracking your progress through RPE can be very helpful in determining your limits.

      Honestly, the way I see it, form over everything. You can do all the curls in the world, but if your form sucks, you'll end up with nothing but a bad back.

      Another thing to consider is the range of motion. Hammer curls let you use heavier weights, while reverse curls may feel more controlled. Switching up your grip every few weeks can help with progress too.

    I have to agree with some of the others here. Both curls serve a purpose. Nutrition also plays a huge role, so don't neglect your meals. I always plan my post-workout snacks!

    Both exercises have their merits, but if you're looking for gear to enhance your performance, consider wrist wraps for reverse curls. They can help with stability and prevent strain. Just make sure your form is solid

      Lol, I never do either because I just drink my coffee and call it a day. But, if you wanna hit those arms hard, do both!

    Facts! Both exercises hit different parts of your arms. Mixing them up can keep things fresh too!

      I actually prefer doing them back to back sometimes, just to really fatigue my arms. It's killer but worth it!

      Yeah, I'd say don't stress too much about which is better. Focus on what feels right for you and track your progress. That's how you really see results.

  I love doing both! I usually do hammer curls on upper body days and reverse curls on lower days. It helps keep my routine balanced and my arms feeling strong!

    Listening to your body is crucial. If one exercise feels off or causes pain, switch it up. That will help with long-term progress too.

    It's all just a hamster wheel. You lift, you eat, you repeat. But sure, have fun with your hammer and reverse curls. Just don't expect miracles.

    100! Gotta keep that variety alive! I did both for a while, and my arms were pumped.

    Also consider your overall workout split. If you're hitting arms frequently, you might want to vary rep ranges between the two to maximize gains and avoid plateaus. 3 sets of 8-10 for hammer curls, then 4 sets of 10-12 for reverse curls could work.
