Do you take rest days?

3 days hard at the gym, about 2 days a week doing bodyweight, mobility, and GPP stuff at home. Walk everyday with the dogs and family.

Sometimes I'll skip the home workouts if the baby isn't letting me sleep much or I'm just tired.

Nope. 24/7 grinding

So much assumption

Mondays are for rest. Every fourth week is scaled back too. My basis is cycling not weights, tho.

Working out tears muscle down, rest re-builds it larger than before. If all you do is workout and not rest, all you do is tear muscle down.

Are you suggesting take a full day of rest to recover in between every workout, twice a week or possibly more?
My workouts target one major muscle group each day with time in between the next workout of that same main muscle group coming after about 6-7 days. Such duration in between workouts will typically have me lifting close to 25 days out of the month.
I take BCAAs during every work out, creatine after and plenty of whole foods to keep my body fueled up. The reason I mention this is because I feel great in terms of energy, and fatigue isn't really the issue, nor is recovery (good sleeper I suppose), but my gains have been incrementally slowing down to the point where it feels more like maintenance than improvement. Does that have something to do with the volume of workouts I'm doing, and would adding more days off to recover increase the rate of improvement?

Saturday and Sunday

Don't know how people go nonstop. I'd be burned out.
