George Baldock has revealed some of the finer details of the players training schedule after it was confirmed the Blades had returned to Shirecliffe earlier this week.
Individuals are now reporting to United's training base for specific sessions but social distancing protocols are being strictly adhered to given the ongoing Covid-19 pandemic and Baldock says the graft hasn't stopped despite the prolonged lockdown.
He remarked: "We're given time slots, you're on your own, the sessions are already set up, one member of staff is with you, but at a distance. He's got the stopwatch ready and he explains to you what you have to do, and it's over to you.
"It's good for them to just see how you are physically and mentally. Even though you are at a distance, the staff can gauge how you're doing, you can have a five-minute chat and it's good to get on a good surface again.
"Now training has been ramped up, we're twisting and turning so it's important that we're on a good surface rather than lads twisting and turning on the road."
Baldock added: "I feel up to speed now. The training we've been given, I can't begin to tell you how tough it has been. Some days it's been like pre-season. I've woken up today after the last two days with my legs in bits, it's tougher than a lot of sessions we've done at Shirecliffe this season.
"I'm sure the other lads will be saying the same as me, everyone will be fit, there's no cutting corners and like I said everything is recorded so everyone has been doing every session.
"I don't mind training alone, I enjoy trying to try better myself in the off-season and getting the work done. But it's a terrible situation at the minute and to get the opportunity to go to your place of work and to do what you love on a good surface, it's the best of a bad situation."
