The part I find that's really grindy is when you are training by the boulder and meditating in the hut.
The physical training can be done in "batches". You can do that by toggling the button on the screen prior to training.
(It's the orb that looks like a recycle symbol).
As for the meditation, and the "batch" training, there is a reason for why they are structured the way they are.
As you grow more powerful, you will be able to train for longer periods, sometimes days and even months. This is pretty normal in a cultivation fantasy. You can cancel these activities at any time during the process (for both meditation and physical training), for that reason I doubt that I will change the way those mechanics work. The idea being that you can split up your energy however you like between those activities, then go do other things if you have sustenance left.
(Above is an example of "batch" training your Martial Skill.)
This isn't too important right now, but later on in the game it will be very important. Especially if you want to split your time between 3-5 activities (like exploring, crafting, training, meditating and socializing -- all of which require sustenance to some degree). Also later in the game, once you become an official student of the Golden Lotus Academy, you will also need to do time sensitive tasks for your academia.
All of these aspects together, once implemented, will give you a wide range of ways to spend your time and energy.
