"I look at all the hurdles I have overcome these last couple of years with glandular fever, injuries galore that have been non-stop. Along with having access to all this injury management and prehab stuff, and doubling my training, I really feel we can do some special things next season.
"I will be aiming to improve my times because if times come, titles come. The whole mentality of this campaign has changed and is different to how I have ever felt before.
"I am more excited, I am more passionate, I am more hungry. I believe in everything me and coach are doing which bodes well for the future."
Hill said Harman's commitment and confidence had sky-rocketed since winning the national title last summer.
"He is now full time so I have two sessions a day with him with the majority at Aspire, some at the track and a few parks. All the power and acceleration and recovery stuff is done there too," Hill said.
"Kodi will have a pretty good shot at the Rio Olympics. With his talent and the opportunity to train full time, the target is just within his capabilities, I think. His 200 has to be 20.5, about .7 quicker than he has ever run, but he hasn't run a serious 200 for two years. Now he is doing real serious training for that.
"The 100m target is in the 10.1 vicinity with 10.42 his best time two years ago. Last year, he had all sorts of aches and issues to deal with."Any fool can work out he is going to make massive progress."
Hill is particularly excited about the indoor sprint track at Aspire.
"Having the indoor track with the surface it has means we can run in lightweight flats or bare feet. Bare feet are very important because of all the work the feet do. Other times they are protected by shoes and they lose tone in that critical stability base, and that manifests itself through the legs right up to the lower back at least."
