Arm Stress
Score
Your arm is your career. Log every throwing session and BaseballFit turns it into a daily arm-stress score — a clear read on when to push and when to back off. When stress runs high, your workout automatically reshapes itself so you keep training without overloading your arm.
- ▸Time-weighted 7-day score — recent throws count more, older ones fade as your arm recovers.
- ▸High stress auto-shifts your session to lower body, core, and arm-care work — a productive day, not a lost one.
- ▸Tell it how your arm feels before and after you throw. A sore arm after a session shuts down any more throwing that day.
- ▸Workload Trend Pro compares this week’s throwing with your last four, so a sudden spike shows up before it becomes a problem.
- ▸Age-adjusted, and the score itself is free for every user, forever.
Throwing
Plans
Pick a program and BaseballFit hands you each throwing session — the drills, the throws, the distances and how hard to let it go. Six plans built from 72 authored sessions, and every one of them answers to your arm first.
- ▸Distances scale to your own long toss, not a chart built for someone else.
- ▸The plan moves forward only when you finish a step. Miss a day and you pick up where you left off — nothing gets skipped.
- ▸It never overrides your arm-stress score. If your arm is sore, today’s session waits. Pause or quit any time.
- ▸A Pro feature for throwers 10 and up, with a quick safety check before your first plan.

Muscle Readiness
System
Stop guessing which muscle groups are ready to train. Our time-based recovery model accounts for training intensity, muscle size, and eccentric load across 8 key groups.
Game Plan
Every athlete gets a plan built around their position, season phase, and readiness — not a generic template. BaseballFit rebuilds your daily session from the ground up so the work always fits the player.
- ▸Position-specific programming for pitchers, catchers, and position players.
- ▸Auto-periodized across off-season, pre-season, and in-season phases.
- ▸Recovery days and deload weeks are earned from the work you’ve actually logged — and after a layoff, the first two sessions ease you back in.
- ▸Short on time or gear? Build your own workout — or with Pro, swap today’s focus or add a bonus session.
Coach's Call
Tap any exercise and get a straight answer to “why am I doing this?” Coach's Call turns the math behind your plan into plain-language coaching — right when you're doing the work.
- ▸Explains why each exercise is in your plan and what it builds for your game.
- ▸Tells you why today's weight, reps, or sets changed — progression, deload, or a hard-earned jump.
- ▸Talks like a coach, not a spreadsheet — and adjusts its voice for younger athletes.
The Dugout
Train on your own, compete as a team. Start a Dugout, send the invite link to your teammates, and every week the Lineup ranks who showed up — scored on following your own plan, not on who lifts the most.
- ▸Half the score is doing the sessions your plan calls for. The other half is logging your throwing — even a day you didn’t throw counts.
- ▸Rest and recovery days never cost a point, and arm health never enters the score. Nobody gets rewarded for training through it.
- ▸Invite-only, no chat and no feed — the team name is the only thing anyone types.
- ▸A Pro feature for players 13+.
