Let a split decide for you
A structured split removes the daily guesswork. Upper lower four days, or push pull legs, means you always know today's job and every muscle gets trained about twice a week.
How do I know what to train today?
Follow a set split so the decision is already made, and if you have no plan, train whatever you have not hit in 2 to 3 days.
The quick answer
The easiest fix is to run a fixed split so today's session is decided in advance, upper lower, push pull legs, or full body on a schedule. Without a plan, pick the muscles you have not trained in the last 2 to 3 days, since each muscle recovers and is ready to grow again in about 48 to 72 hours. Aim to hit every muscle twice a week rather than random one off sessions.
How to think about it
Use the 48 to 72 hour rule
Muscles are recovered and primed to grow again 2 to 3 days after training them. If you are freestyling, train what you have not touched in that window, and let lingering soreness push a muscle to the next day.
Balance push, pull, and legs
Over a week, make sure pressing, pulling, and lower body all get roughly equal attention. A tool like SUUPR can track which muscles you have hit so you can spot what is falling behind.
Do this
- Pick a splitUpper lower or push pull legs turns the daily question into a fixed answer.
- Recall your last 3 daysTrain the muscles you have not worked in 48 to 72 hours.
- Aim for twice weeklyEach muscle trained about two times a week beats random single hits.
- Respect sorenessIf a muscle is still notably sore, train a different area today.
Keep going
