Yep. Everyone is different. Some recover faster or slower than other.
It could also be something to do with your lifestyle or training. Lack of sleep, stress, high volume workouts, training age (for a specific exercise), rest between workouts, leisure activities. I could go on all day (or at least a few more lines lol) but sufficed to say everything has its hat in the ring.
If your recovery has always been on the slow side, but has recently become much slower, take a look at anything that has changed lately. A few things can add up to a bigger impact. Don't forget about your recent diet shift, that's a biggie sometimes.
