Dumbbell curls and pushdowns work, but they lose tension the moment your arm straightens or the weight swings with momentum. Cable arm exercises keep your biceps and triceps loaded through the whole rep. Below are five cable arm exercises worth adding to your functional trainer routine, each with a quick how-to.
Why Cables Are Great for Arm Training
A dumbbell curl loses most of its resistance at the top and bottom of the rep, the two points where gravity stops pulling against your arm. Your biceps get a break right when you're locked out, and again right at the bottom before the next rep starts.
A cable doesn't give you that break. It pulls at a consistent angle through the entire movement, so your biceps and triceps stay under tension from the first inch to the last. For anyone new to arm training, that's the real reason to add cables to a routine built on dumbbells and barbells: more time under tension per rep, with less room to cheat the top or bottom of the movement.
5 Cable Arm Exercises to Add to Your Routine
Two of these work triceps, two work biceps, and one crosses over into your forearms. Start with one pushdown variation and one curl variation, and use the rest to add variety later.
Cable Tricep Pushdown
Set a single pulley high, push the handle or rope down until your arms are fully extended, then control the return instead of letting the weight stack slam. Keep your elbows pinned to your sides so your shoulders don't take over the movement.
Cable Bicep Curl
Set both pulleys low, curl the handles up toward your shoulders, and keep your elbows pinned to your sides so your shoulders don't take over the movement. The constant tension from the cable makes the top of the curl just as demanding as the bottom.
Cable Hammer Curl
Set both pulleys low, curl the handles up with a neutral grip so your palms face each other, and keep your elbows pinned to your sides. The neutral grip shifts more work to your forearms and brachialis than a standard curl does.
Cable Overhead Tricep Extension
Set a single pulley low, face away from the machine, and extend a rope or handle overhead until your arm is straight. This angle stretches the long head of your triceps more than a standard pushdown, which makes it a strong pairing with the pushdown above.
Cable Reverse Curl
Set both pulleys low, curl the handles up with an overhand grip instead of the usual underhand grip. This shifts the work toward your forearms and brachioradialis, a spot most curl variations barely touch.
Building a Cable Arm Routine
Pick one pushdown variation and one curl variation per session, then rotate in the others every few weeks. Two exercises per arm group is plenty when the tension stays constant through every rep.
Here's the number that matters if you're comparing functional trainers for arm work: pulley ratio. A lot of machines run a 2:1 ratio, which cuts the felt resistance roughly in half compared to the number on the weight stack. The Dane 2.0 runs a true 1:1 ratio, so its 160-pound stack per side gives you 160 pounds of real, honest resistance on every curl and pushdown in this list. We test each of these movements on our own Dane 2.0 before we recommend them, and the Fringe Fam does the same in their own garages every week.
Cable Machine Basics: What You Need to Know First
Before you touch a single cable, there are three things worth understanding: pulley height, attachment type, and pulley ratio. Get these right and every exercise below makes sense. Skip them and you're just guessing.
Pulley height. Most cable machines let you set the pulley high, low, or somewhere in between. High pulley means the cable comes down from above your head, the setup for pushdowns and extensions. Low pulley means the cable comes up from near the floor, the setup for curls.
Handle vs. rope. A straight bar or handle keeps your grip fixed and works well for pushdowns and curls, where a locked wrist position is fine. A rope attachment lets your hands move independently, which matters for movements like the reverse curl and overhead extension, where a slightly different angle changes which muscle does the work.
Pulley ratio, and why it matters more than the number on the stack. This is the part most newcomers never get told. A lot of functional trainers run a 2:1 pulley ratio, which means the resistance you actually feel is roughly half of what the weight stack says. Load 40 pounds and you're lifting closer to 20. The Dane 2.0 runs a true 1:1 ratio, so its 160-pound stack per side gives you 160 pounds of real, honest resistance on every curl and pushdown in this list. Check the ratio before you check the price tag. It's the number that tells you what you're actually getting.
Frequently Asked Questions
Why is the tricep pushdown so much more popular than other arm exercises? It's simple to set up, easy to load heavy, and works on nearly any cable machine. That makes it one of the most searched single exercises in strength training, not just on a functional trainer.
Should I train biceps and triceps in the same session? Most lifters do, since both muscle groups recover quickly and pair naturally with a pushing or pulling day. One curl and one pushdown variation per session is a reasonable standard.
Bottom Line
Cable arm exercises solve the same problem here that they solve everywhere else. You get constant tension instead of a rep that gets easier at the top or bottom. Start with a pushdown and a curl, add the hammer curl and reverse curl for variety, and you'll have a complete arm routine from one frame.
