Looking  for a routine to blow those guns up in a hurry? Look no further! We all know how important it is to train legs, chest, shoulders, and back with reckless intensity, but every guy wants to improve the most visible mirror muscles – his arms! These workouts will have you filling out your shirts in 4 weeks flat; no more baggy sleeves!

The Split

Frequency is the name of the game when you’re trying to improve a week body part, and you need to organize your entire split accordingly. Your arms can really take a beating and be ready for more in days, so we’re going to schedule two arm-focused workouts per week. To allow for adequate rest, you’ll need to consolidate the rest of your week as follows:

Day 1: Arm Workout 1
Day 2: Legs
Day 3: OFF
Day 4: Chest and Shoulders
Day 5: Arm Workout 2
Day 6: OFF
Day 7: Back

Don’t worry, your chest and shoulders won’t shrink without entire days of their own! One workout still leaves plenty of time and energy for one or two bench press variations, an overhead press, and a few different flyes and side raises. By consolidating these parts into one day, you also leave more time for extra arm workouts and adequate rest – the two things you’ll need most to grow those guns!

On the legs and back days, train as you normally would. Squats, deadlifts, leg presses, rows, and pull-ups – the stuff you should be doing year-round. Make sure you keep up the intensity on these days, especially when you train back. Your arms won’t grow if you’re not gaining overall strength and body weight, so don’t think you can afford to dedicate your whole damn week to curls and extensions!

Without further ado, here are your twice-weekly arm workouts for this four-week routine. Always warm up with 50 – 100 easy reps of very light curls and extensions before you get started. You don’t want to fatigue your arms before the real work gets under way, but you do need to get plenty of blood into the muscles before you handle heavy weights.

Super-set cable push-downs and cable curls: 3x 20 for each exercise

Eat to Grow!

No matter how pumped your arms feel while you’re training, they’re never going to really grow until you eat and rest. Like every other body part, your arms will only grow if you’re gaining strength and muscular body weight, so get plenty of clean food and sleep. With enough dedication, you’ll be amazed at how fast you can progress in just 4 weeks!
