Aside from that, having health issues even if younger, I was surprised how valuable deadlift (with 5 to 10kg kettle bells) and squats were important for your body. The ability to go down softly without efforts or joint pain is such a relief.
Total anecdote, but aside from injuries and a brief period of wildly overtraining for university rowing, I have _never_, in my life thought after exercising "I feel worse than I did before starting". It's basically the magic pill.
but I used to run / bike, and this didn't address the same movement as deep squat / dead lift affect
Your legs and your back are the two muscle groups you use the most. You always want to have good posture (deadlifts) and you always want to be able to move around easily (squats). Being the guy that opens any jar of pickles is cool and all, but those two alone definitely increase your QoL.
