How to Use the Attempt Selection Calculator: A Complete Guide

The Attempt Selection Calculator turns your estimated true 1RM into a suggested opener, 2nd, and 3rd attempt — a starting plan you walk into the venue with, not a rigid script you’re locked into once the bar starts moving.

Why attempt selection is its own skill, separate from strength

More meets are lost to a badly chosen opener than to simply not being strong enough. A missed opener doesn’t just cost you one lift — it forces your 2nd attempt to also function as an opener, compressing your entire meet and usually costing you any real shot at a third-attempt personal record. Picking good attempts is a genuinely separate skill from training, and it’s one that’s easy to under-practice since you only get to rehearse it a handful of times a year at actual meets.

Step-by-step: how to use the calculator

  1. Choose the lift (squat, bench, or deadlift) — this is for labeling the output only; the underlying math is identical for all three lifts.
  2. Toggle kg or lb.
  3. Enter your estimated true 1RM for today. This is the single most important input, and the easiest to get wrong — use your realistic current max, not your all-time best-ever number from a different training cycle.
  4. Pick a strategy: Conservative, Standard, or Aggressive.

What each strategy actually changes

Conservative uses a smaller opener-to-third jump — roughly 88% / 94% / 99% of your estimated max — built for banking a total you’re very likely to complete in full. This suits lifters newer to competing, anyone prioritizing a clean confidence-building meet, or situations where simply finishing with a total matters more than chasing a specific number.

Aggressive stretches those percentages higher — roughly 93% / 98% / 104% — for a lifter specifically chasing a personal-record total and willing to accept meaningfully more risk of a missed attempt in exchange for a shot at a bigger number.

Standard sits between the two, and is the reasonable default if you’re not sure which situation applies to you.

Use it as a starting point, not a contract

The single biggest mistake lifters make with attempt selection is treating the plan as fixed the moment they’ve written it down. Your calculated numbers are a sensible starting point built from an estimate — but the bar itself gives you real information on meet day that the calculator can’t know in advance:

  • If your opener moves noticeably faster than expected, there’s genuine room to push the 2nd attempt harder than originally planned.
  • If your opener grinds or feels heavier than it should, a more conservative 2nd attempt that you actually make is worth more — for your total and for your confidence walking into the third attempt — than an aggressive one you miss.
  • Bar speed, not just how the weight “feels,” is the most reliable signal coaches and handlers use to adjust attempts in real time.

A note on estimating your “true” 1RM

The quality of your attempt plan depends entirely on the quality of that first input. If you don’t have a recently tested 1RM, the One Rep Max Calculator can estimate one from a recent hard set — but treat that estimate conservatively going into a meet, since rep-max formulas get less reliable the further the set was from a true single-rep effort.

Common mistakes to avoid

  • Using an old PR instead of today’s realistic max. Strength fluctuates across a training cycle; plan from where you actually are now.
  • Refusing to adjust after the opener even when the bar speed clearly signals you should.
  • Picking Aggressive without having banked a total before. Chasing PRs on every attempt at your very first meet is a common way to walk away with no total at all.

Frequently asked questions

Should my opener always be a lift I’m 100% certain to make?
Essentially, yes — its entire job is getting a number on the board and building confidence for what follows, not testing your limits.

Can I use different strategies for different lifts in the same meet?
Yes, and many experienced lifters do — for example, playing conservative on a lift they’re less confident in technically, while being more aggressive on their strongest lift.

How much should I trust the exact numbers this gives me?
Treat them as a well-reasoned starting plan based on common coaching guidelines, not a guarantee — your own recent training data and how you feel on the day should always take precedence over any calculator.

Should a coach or handler override this plan on meet day?
Absolutely, if you have one available. A calculator can’t see your warm-up bar speed or hear how you describe a lift; a good handler watching in person has real-time information this tool simply can’t access.
