The Reds started full contact training last week as they prepare to wrap up the Premier League, needing just two wins from their last nine matches.
"So far, so good," said the England right-back. "It has been positive to be back with the boys, that was the main thing we've all been missing.
"It's just really positive, everyone is in a good mood and good spirits. We're just happy to be back.
"Obviously it's safety first, so we've had to take precautions and take it seriously but, when we get into training, it's good to be back to normal."
