Ideal 4-5 day Workout Split

An ideal workout split can be objective, but I believe 4-5 days is optimal to allow for rest days in between for the muscles to recover. If you workout everyday, you may overtrain your muscles and be sore which can effect the next workout leading to a less effective workout. 

That is why finding balance is ideal to fit into your lifestyle. I personally train specific muscles groups to optimize recovery and development. I am into calisthenics, but if you prefer a gym that is fine as well. I aim to workout 4-5 days a week and I will take you through my routine. 

Day 1: Chest/Back

I work these muscles groups as they are opposite to one another and work in tandem with one another. By exercising your back and chest, it allows for a balanced development and overall better posture if trained with correct form. 

For Chest exercises I do include:

1. Push-ups (Various elevations to target different muscle groups in the chest, Decline, incline etc.)

2. Dips

If in a gym, you can do the barbell bench press and cable/dumbbell fly's

For Back Exercises:

1. Pull-ups

I keep my movements simple and controlling my body movement is most important to master. 

If in a gym, you can do Lateral pulldowns, bent-over rows, and dumbbell rows

Day 2: Legs/Abs

Balence is key and as you work your chest/back, it is important to stay balanced and train your legs and core as well. 

For Leg exercises, I do: 

1. Squats

2. Lunges

3. Calf Raises

4. Jumping Jacks

5. Outdoor Walking/Running

If in a gym, you can also do leg press, leg curls, treadmill, or standing bicycle instead.

For Abs, I do: 

1. Planks

2. Hanging Leg raises

3. Bicycle crunches

4. Mountain Climbers

5. Reverse Crunches

Day 3: Rest Day or Active recovery

Ideally, this is a type of day that is low intensity like walking or stretching/yoga or fully take a rest from working out. These low intensity exercises can help increase blood flow to your muscles and aid in the recovery process to be ready for the next session. Always ensure your body is properly hydrated as well.

Day 4: Repeat Chest/Back day above

You can do the same exercises as above or experiment with other exercises with what works best for you and your body.

Day 5: Repeat Legs/Abs day above

Day 6: Rest Day or Active recovery as above

Day 7: Rest Day or Optional to workout 

Feel free to take the 3rd rest day of the week or pick 2-3 body parts to work out like above. If I don't use this as a rest day, I will usually work on 2-3 body parts I want to grow and prioritize it.

In conclusion, alternating between chest/back and legs/abs allows for a well-balanced physique and overall to a balanced training. Tailor the training to your personal goals and do feel free to customize this as you see fit into your personal goals. Consistency and proper nutrition are needed in conjunction with a workout plan like this to achieve your desired results.
