Phaserr is a program builder for strength and conditioning coaches. You write the program, Phaserr does the math and gets it to your athlete’s phone.
The problem
Most serious strength coaches write their programs in Google Sheets and a notebook. Not because they love it. Because nothing else accepts the way they write: blocks, phases, percentages of 1RM, their own progression rules.
I talked to a lot of coaches before building anything. Personal trainers manage fine with a notebook. They adjust on the floor, client by client, and the notebook keeps up. Powerlifting and S&C coaches are the ones stuck. Their program is weeks of thinking, structured work, and the best tool anyone gave them for it is a grid of cells.
And the manual work never stops, because a program changes all the time:
- The planned weight turns out to be too much, and the athlete underperforms.
- Or it’s too easy, and the load can go up.
- The gym doesn’t have the equipment the plan calls for.
- An exercise presses on an old injury, or something just feels wrong, and needs a replacement.
- And at the end of the block, test day brings a new max. The next block starts from the new number.
In a spreadsheet, each of these means rebuilding cells by hand. Per athlete. In a separate file. Then the updated program goes out as one more screenshot.
The apps don’t save you here. The good ones are made for people who train themselves: pick a template, enter your maxes, follow along. The platforms made for coaches let their AI write the plan while you approve it. If your athletes pay you for your programming, you can see the problem with both.
How Phaserr solves it
Build. Blocks with linear, step or undulating progression. Loads from %1RM or a training max. Warm-up sets calculate themselves. Save any block as a template and reuse it. Add your own exercises. Group your warm-ups and conditioning into collections and drop them into any training day. Want a head start? Describe the block, and Phaserr drafts it from your exercise library and the athlete’s real numbers. You review, change, save. Nothing goes live without you.
Adjust. Too heavy, too easy, no equipment, a problem exercise, a new max after test day. You change the program in place and the math recalculates. The athlete’s side updates by itself. Nothing to rebuild, nothing to re-send. This is my favorite part of the product, because it’s the part the spreadsheet punishes you for the most.
Share. A remote athlete gets a link. It opens on their phone, no account, nothing to install. Or send the program as a normal message in a messenger. Or a PDF. And when the athlete trains next to you, open the same view on your own phone (it’s called Focus mode) and track the exercises right from the floor.
Track. One calendar per athlete: which days are completed, which are not, which exercises came in under the plan, week over week. If you coach remotely, this is the difference between the real picture and “all good, coach.”
One rule holds all of it together: the program is the coach’s craft. Phaserr does the math and the delivery. It will never write the program for you.
