- Why I built ChangoThe short version: none of the gym apps I tried fit my life.
- When should I increase the weight?The short version: add weight when you can do the top of your rep range in every set and it still doesn't feel too hard.
- Full body or split routine?The short version: both work, as long as each muscle gets enough work over the week.
- Which workout app shows the muscles you trained?The short version: Chango shows every muscle you trained on a 3D figure.
- How many days a week should I go to the gym?The short version: two or three days a week is enough for most people to get stronger and build muscle, as long as every muscle gets enough work over the week.
- How long should I rest between sets?The short version: about 2 to 3 minutes after big exercises like squats, presses and rows, and about 1.5 minutes after smaller ones like curls.
- How many sets should I do to build muscle?The short version: two to four sets per exercise, and over the week around 10 hard sets per muscle or more, which research links with more growth.
- Can you get too big muscles from training?The short version: not by accident.
- What to do at the gymThe short version: warm up with a light set, do the big exercises that use many muscles first and the smaller ones after, take a few sets of each with proper rests in between, and over the week make sure every muscle gets enough work.
- How to start gym trainingThe short version: two or three workouts a week, your whole body each time, a few sets per exercise with weights that feel hard by the last reps, and a little more whenever it starts to feel easy.
- What is Chango?Chango is a gym workout app that plans your workouts for you and shows every muscle you've trained on a 3D figure.
