I know this a fitness sub, but I know most people here workout.

For the year and a half I’ve done a upper lower split.

I’ve gotten up to 165 at 5”8, if I take a shirt off I look decent, abs visible if flexing.

I recently switched to a 5 day routine,

1:chest/shoulders/tris 2:back bicep 3:legs 4:arms 5:shoulders With 2 rest days mixed in there.

I’m trying to gain muscle and size .i have plateau. I feel like once a week is not enough.

What do you guys recommend ?
