The perfect workout program on paper is useless if your schedule makes it impossible to follow.
Instead of copying someone else's routine, build a program around your availability, experience, and goals.
Choose Your Training Frequency
Available Days Suitable Approach
2 Days Full Body
3 Days Full Body
4 Days Upper / Lower
5 Days Upper / Lower + additional training
6 Days Push / Pull / Legs
Build Around Major Movements
Your routine should include exercises covering major movement patterns such as:
Squatting
Hinging
Pushing
Pulling
Carrying
Core stabilization
Keep It Sustainable
If you can realistically train four days every week, a four-day routine is better than a six-day program you constantly miss.
Final Tip
The best workout routine is the one that fits your life well enough for you to follow it consistently.
