Eh, it really depends how heavy your clutch is. Exonoboxes (Saturn SL2, Sonic) or sporty cars with lower torque numbers (Miata, Celica, Fiero, Prelude, S2000) = no biggie. Higher torque (V8 Camaros and Trans Ams, Corvettes) usually have an assist spring to help you hold the petal to the floor, but engaging/disengaging take more leg effort.

On a side note, modern manuals kind of suck. They hold revs when you pop the clutch for emissions reasons, which makes the 1-2 shift especially kind of suck. A lot of them also barely engine brake and dual mass flywheels on higher output engines can clunk if you unload them hard. Although regen braking isn’t super thrilling, it’s way more engaging that engine braking in basically any model year 2010+ vehicle.
