Used to be 170lbs now 150lbs lean need help

[Itswar]

I used to be 170 and was lean then starting playing football more more cardio and diet wasnt that good so went down to 150 I was just wondering because I was at 170 before and because of muscle memory would i be able to put the 20lbs at a faster pace

theoretically, sure.

In anycase, muscle memory or not, have a calorie surplus and you will put on weight
