One Rep calculator
Want to know the heaviest weight you can lift for just one go? That's your one rep max (1RM) – the peak weight you can handle for a single lift, be it a squat, bench press, deadlift, or any other exercise. For safety and effectiveness, using a one rep max calculator can give you a solid idea of what weights you should be attempting.
Your 1RM is also pivotal if you're following the Maximal Strength phase of the NASM OPT™ Model. Here, you'll typically be lifting at 85-100% of your 1RM, so knowing your limits ensures your workouts remain challenging yet safe.
After plugging in your lift numbers, you'll see a breakdown that shows where you stand with your max lifts. And, don't make the mistake of thinking your max on one lift applies to another – your bench press 1RM might be worlds apart from your back squat.
Keep in mind, these figures are ballpark estimates. If you're unsure, chatting with a personal trainer can offer some clarity (or start the journey of becoming a coach yourself).
