Circuit training for general fitness

Give every block a reason.

Circuit training for general fitness works when each part of the week has a job. Decide what needs to improve, what supports it, and what can stay simple.

A flexible format for strength endurance and time efficiency. Complexity is only useful when it changes a decision you could not make with a simpler plan.

Control the variables.

Keep enough of the program stable to see whether the change helped. Change frequency, volume, exercise selection, or effort with intention instead of changing everything at once.

A useful program tells you what to do on a normal week and what to do when the week becomes difficult.

Let the plan learn.

Review the block at a sensible interval. Keep what created progress, remove what created unnecessary friction, and make the next version slightly more precise.
