Bigger arms can be acquired through bodyweight training. If you train intelligently and follow simple progressions, you can get pretty close to your maximum natural arm size by doing solely bodyweight exercises.
One of the better bodyweight exercises for the biceps are pull-ups on rings. The rings allow your wrists to rotate freely, which reduces the stress on the joints.
For triceps, close grip push-ups and parallel bar dips will work great. When you combine them with dips, you have a recipe for larger triceps.
The routine below may be hard for a complete beginner. You may even have to lose weight before starting it. We recommend that you do it with junk free diet and moderate cardio.
Day 1: Biceps emphasis
Ring pull-ups – 8 sets of as many as you with good form
Close grip push-ups – 8 sets of as many as you can with good form
Day 2: Rest or “leg day”
Day 3: Triceps emphasis
Dips – 8 sets of as many as you with good form
Australian pull-ups with rings – 8 sets of as many as you can with good form
Day 4: Rest
Day 5: Recovery and/or “leg day”
Push-ups – 5 sets
Australian pull-ups – 5 sets
Day 6 & 7: Rest
Once you have reached 10-12 pull-ups and 15-20 dips for the initial sets, consider adding weight or reducing the rest between sets. Always follow proper form. Don’t cheat by swinging your legs and cutting the range of motion.
What progression should I follow?
Add 1-3 reps to your initial sets every week. If you try to progress every session, you will stall quickly. It’s better to follow a weekly progression.
Is this the ultimate way to build your arms?
Truth be told, there’s nothing magical about this approach. It’s not superior to regular weight training. But if you progress and eventually add weight, your upper body and arms won’t have a choice but to respond. Yet some regular curls could also be highly beneficial, although you may have to reduce the pulling volume to make space for them.
