About this app

"You can always start again."

I stopped working out because I was too busy.

I've been away from the gym for months.

I feel like if I slack off once, I'll never be able to get back on track.

I blame myself for not being able to continue, and then I stop again.

Re:Start Fit is an app for people like you who are thinking about "returning to the gym" or "restarting weight training."

━━━━━━━━━━━━━━━━━━━━━━
■ What is Re:Start Fit?

━━━━━━━━━━━━━━━━━━━━━━

It's a community app for people who want to "restart" weight training.

It's not a hard training log app.

It doesn't ask about weight or sets.

It only asks two things:

"What did you do?" and "How long did you do it?"

Even a 10-minute home workout counts as one session.

Whether it's your gym workout, bodyweight training in the park, or stretching at home, you can record it all the same way.

This is a community specializing in helping people restart their workouts—for those who have quit strength training many times, those who have had long breaks, those who give up easily, or those who couldn't stick with going to the gym.

━━━━━━━━━━━━━━━━━━━━━━
■ Features
━━━━━━━━━━━━━━━━━━━━━━
▸ Record in 10 seconds
Simply select what you did and the time. Photos and short messages are optional.
We've lowered the barrier to posting to the absolute minimum.
You can record any workout—home workouts, gym workouts, bodyweight training, cardio—anything.
Many people stop strength training because "recording is a hassle." We've made it 10 seconds.

▸ No comparison, no competition
There are no rankings or follow functions.
Everyone is in the same lounge, supporting each other's return to training from the same perspective.

A relaxed atmosphere that allows you to continue without being overwhelmed by the flashy posts of hardcore trainees.

▸ Stamps to celebrate your return

Six types of original stamps to acknowledge each other's efforts, such as "Nice 👍," "Great job continuing 🏅," and "Good sweat 🥤."

Not just a "like," but a feeling of "Welcome back."

The first post after a long break is the one that deserves the most praise.

▸ Restart Mode (First 30 days free)

You can experience all functions for free for 30 days after registration.

No quotas. You can start at your own pace.

The first 30 days are a test to see "whether you can start again."

▸ Record screen that shows your progress

Number of posts this month, number of training days, number of consecutive days, total time.

Small accumulations are clearly "visible."

Visualizing your sense of accomplishment is necessary to make strength training a habit.
▸ Number of times you've returned = Your strength
No matter how many times you quit, we'll record the number of times you've started again.
There's more value in coming back multiple times than in perfect consistency.
"A third restart" is far stronger than "a one-year break."

■ How to Use It in Different Scenarios
━━━━━━━━━━━━━━━━━━━━━━

▸ For Home Workouts
Even 10 squats, a 1-minute plank, and stretching at home can be recorded as legitimate "workouts."
It's designed to accurately record even bodyweight exercises without equipment.

▸ For Those Aiming to Return to the Gym
Start by getting your body used to it with home workouts before heading to the gym.
Even if you've been away for six months, a year, or several years,
you can slowly build up your fitness starting with just one 10-minute home workout.

▸ For Those Aiming to Overcome a Lack of Exercise
Not just strength training, but walking, yoga, and stretching can also be recorded.
It can also be used as a habit-forming app to accumulate "time spent moving your body."

■ Frequently Asked Questions
━━━━━━━━━━━━━━━━━━━━━━
Q. Is it okay for beginners in weight training?
A. Absolutely. Re:Start Fit is not for hardcore trainees, but for people getting back into it, beginners, and those who have been away from training for a while. Even just 10 minutes of home workouts is fine.

Q. I tend to give up easily, will I be able to continue?
A. It's designed to record "the number of times you start again, no matter how many times you stop," so it's okay if you don't stick with it. The number of times you return is what makes you strong.

Q. Can I record weight and sets in detail?
A. It's intentionally designed so you can't. We've lowered the barrier to recording as much as possible, prioritizing easy continuation.

Q. I couldn't stick with going to the gym, can I use this?
A. You're more than welcome. This is a community for people who couldn't stick with the gym, those with a gap in their fitness routine, and those who prefer home workouts.

Q. Is posting photos mandatory?
A. It's all optional. You don't have to post photos or even a single comment if you don't want to. You can participate casually without showing your face or location.
