Yes, you'll have a bodybuilder's body as a baby.
Joking aside, since you have progressed in this field in this lifetime, you may have an "inner" drive that will lead you back to this field in your next lifetime, you may achieve success in this field in a shorter period of time, yet we lose some things in our inter-life reincarnations, but this does not prevent us from regaining them and this time overcoming our previous limits.
