Failure is something you have to encounter countless times, pull yourself out of it and keep going. That is strength, your physical prowess is also strength, your resolve and your determination to keep going when everything in your body is screaming to let go, is also strength. Your inability to give up is strength, your vulnerability and acknowledgment of your own limitations is also strength.

His constant sparring sessions with his disciples where they're being, essentially beat up (that's bound to happen when ur up against an immortal) is setting them up for personal challenges that they will have to overcome themselves. The ability to recognize your own weaknesses and limitations, the strength and discipline to keep going and growing, the resolve and stubborness to stand before your peak lord once again to spar with him, knowing you're gonna get your ass handed to you and then having to do it all over again. True strength. The biggest point to note here is, this is exactly what we see from the peak lord too when he spends 5 years in a deadlock against binghe.

He WANTS his students to be better and more powerful than him so they'll be prepared when the time comes for them to take over.
