Surrey bowler Chris Tremlett is hopeful he can join England in this year's back-to-back Ashes series following his comeback from injury.
Tremlett was a major part of England's series win in Australia in 2010/11, taking 17 wickets in three Tests at an average of 23.35.
The 31-year-old has only played five Tests since, having suffered a string of injuries, but is now making good progress towards full fitness and travelled to South Africa last week as part of a fast bowling training camp.
Tremlett said: "I hope that by the end of the two weeks I will be bowling off my full run at full intensity.
"I'm aiming on bowling four to eight overs every other day.
"The rehab before Christmas was tough. I spent a lot of time on my own in the gym. I wasn't able to bowl then, it was just drills and there was only so much you could do each day.
"In the past six weeks I've made a big jump forward. There's no pain now and I've got to as high intensity as I can in indoor conditions."
He added: "It's unfortunate that the injuries came along when I was bowling well but that makes me think I can get back to that sort of form when I return.
"I never doubted I would get back and with a lot of Tests coming up it is likely someone will go down injured at some point. I know I offer something different."
