Four days per week – that’s all it takes to reap the full benefits of resistance training. A 4 day split workout routine for lean muscle is all you need to build a lean, muscular physique.
While prevailing wisdom suggests that the more we do, the better our results are, there comes the point of diminishing returns.
To that end, we’ve put together a 4-day split workout routine for lean muscle gains. Here is everything you need to know about it:
Your 4-Day Split Workout Routine For Lean Muscle Gains
Each training week consists of two A workouts and two B workouts. Each week, you’ll do two successive workouts – A and B – then take a day off, and have two more workouts.
For example, your training week might look like this:
- Tuesday – Workout A
- Wednesday – Workout B
- Thursday – Rest Day
- Friday – Workout A
- Saturday – Workout B
- Triceps work
How You Do These Workouts Is Of Huge Importance
The goal of each workout should be to train your large muscles first (chest and back, for example), and progressively move to isolation work where you specifically target the smaller muscles – biceps, triceps, shoulders, and abs.
To avoid burnout and severe muscle soreness in the beginning, make each workout about 45 minutes long. You can structure it like this:
- Start with some dynamic stretching to warm up your body.
- Do about 15 minutes of cardio on a treadmill, bike, or Elliptical trainer.
- Do 20 minutes of resistance training.
- Finish the workout with about 10 minutes of HIIT on the treadmill or bike.
Things That Can Make or Break Your Lean Muscle Gains
Muscle growth is an intricate process, and the devil is often in the details. So, here are a few final considerations to keep in mind:
1) To build muscle mass, you need to do resistance training, and your workouts need to be as challenging as your experience allows. Do two to three sets for each muscle and aim for six to twelve reps per set. (1)
2) Since lifting is inherently stressful to the body, you need to provide your muscles with protein as soon as you can. So, have a protein shake within 30 minutes of finishing a workout – that will prevent muscle loss and help you kickstart the recovery process.
3) Though often overlooked, hydration plays a huge role in our athletic performance and training results. So, make sure to drink enough liquids every day, especially on your workout days, as that can play a huge role in your overall results.
4) According to statistics, a whopping 75 percent of Americans are overweight or obese. To avoid this for yourself, do a bit of cardio every day, including on your workout days. (2)
Doing cardio around your resistance training is a great way to burn extra calories, prevent unwanted fat gain, and still build lean muscle with the resistance training.
4 Day Split is Simple and Effective
So, your 4-day split workout routine for lean muscle gain is simple, but also effective. The key is the long game! You have to be consistent, and make it part of your DNA. Your weekly routine, and rarely miss a week.
As you can probably imagine, this routine is incredibly customizable, and you can make it work in numerous different ways.
