Players resumed training this week in preparations for matches to start again next month.
And the league leaders are ready to seal the title race, according to their skipper.
He said: "You need to keep the fitness levels as high as you can, and we were given a programme from the club to do, which was really helpful for us to try to keep some sort of general fitness up so when we do come back in we're at a good enough level to start doing the twisting and turning, the longer passing back into it.
"That's been really good for us and I think a lot of the lads will be at a decent level of fitness so when the time does come where we need to play games, I am sure we will be ready."
Henderson added: "It's been a long time, or at least it's felt like a long time [not playing].
"Obviously it was a little bit difficult not knowing when you're going to go back, so you need to tailor it as best you can, which the fitness staff have done unbelievably well for us.
"We're in a good enough position now to start getting going again, getting the balls out and introducing longer passing and getting the sharpness back, which hopefully won't take too long and we'll be right back at it again."
