CARIUS TRAINING GUIDE
Increase weight when your recent performance shows that the current load no longer provides the intended challenge. A common approach is to use a rep range and effort target: once you can repeatedly reach the upper end with sound technique and appropriate RIR, increase the load modestly and work upward again.
Do not increase merely because the calendar says so. If the last prescription was already at your limit, adding weight can create an impossible next set.
Progression should be constrained by demonstrated performance. Sometimes the correct next step is another rep, another successful set, or simply repeating the load more cleanly.
