What probably is not necessary
Three or more sessions can make it easier to distribute training volume, focus on different muscle groups or pursue more ambitious strength and hypertrophy goals.
You do not need to lift every day. Consistent resistance training at least twice a week is a strong evidence-based starting point for health and strength.

For general health, two strength-training days per week is a well-supported minimum. More frequent training can be useful for specific performance or muscle-building goals, but frequency is only one part of the program.
How Often Should You Strength Train to Actually See Results?
The size of the benefit, who is most likely to benefit, and how well findings generalize beyond the studied populations remain important limitations.
For general health, train the major muscle groups on at least 2 days each week. Progress gradually and choose a schedule you can recover from and repeat consistently.
Ask a question or share your experience.
