Patriots wide receiver Aaron Dobson is anteing up for a season that could define his NFL career.

After a pair of injury-shortened campaigns, Dobson dedicated himself to a new workout plan at Fischer Institute in Phoenix.

Brett Fischer, who runs the facility, has vast experience with the Patriots, as he hosted Darrelle Revis and Devin McCourty among a handful of defensive backs last offseason. He has a history of producing results.

Dobson has been in the program for two weeks and is expected to remain for 6-8 weeks before returning to Gillette Stadium for the April 20 start of offseason workouts.

Fischer has seen a 2013 second-round pick who is motivated to come back strong after a couple of disappointing seasons.

“He was talking about, ‘When I go up there (to Foxboro) and they see me again, I want to make sure they know I’m in the best shape of my life.’ He is really determined,” Fischer said. “That is the underlying theme every day: ‘Hey, I’ve got to be ready when April comes, be ready as far as the best shape of my life.’ It’s frustrating with two years of freaky-type stuff.”

Dobson strained his hamstring while running a go-route against the Packers in Week 13, and the Patriots placed him on injured reserve, though he didn’t require surgery. He only caught three passes for 38 yards in 2014, which was also interrupted on the front end because he underwent major surgery to repair a stress fracture in his foot last March. As a result, Dobson didn’t debut at practice until Aug. 11, so he essentially missed nine weeks of offseason workouts and two weeks of training camp.

Because Dobson and Fischer had never worked together, Fischer spent an hour and a half evaluating Dobson’s prior injuries when he arrived in Arizona to ensure the receiver could be fully cleared for the program. Fischer had no concerns about either ailment but determined it would take almost two months for him to strengthen some weaker areas to prevent similar injuries in the future.

“He is doing great,” Fischer said. “I’m really excited for him. He has put the time and effort into it, comes in early, gets all his work in and he is hungry. There are a few specific things we found, minor little things we’re working on, that make his program a little bit unique to everybody else’s. Nothing major.

“It’s a matter of him developing some areas that were just a little weak and get him back on the field.”

Fischer engineered a unique program to improve Dobson’s strength and flexibility in his lower half. As such, Dobson arrives at 8 a.m. each day for manual work on his legs, ankles and areas of the like. He then goes through dynamic core strengthening to develop his hips and core before a flexibility session to create additional flexibility to help his hips, knees, ankles and lower back. That leads to agility and speed drills. They mix it up with upper- and lower-body days and throw in some yoga sessions, work with the JUGS machine and hold meetings with a nutritionist.

Fischer remains in consistent contact with Patriots head trainer Jim Whalen to update Dobson’s progress, so the workouts are fully supported by the team. Dobson, who worked out at Gillette the past two offseasons, hasn’t employed an independent camp since he attended IMG before the draft, so this new tactic should be beneficial.

He is also working out alongside fellow NFL players such as Michael Floyd, Tyrann Mathieu, Carson Palmer and Drew Stanton. Revis, who has worked with Fischer since his junior year of college, is also expected to make a cameo before April 20.

So far, Dobson has shown Fischer he wants to make it count.

“When I first evaluated him,” Fischer said, “I said, ‘Hey, you obviously had the injury. My goal is to get you better. You’re weaker right now. We’ll get you stronger.’ He said, ‘I’m dedicated to this. Let’s go. I just want to turn my career around.’ I have a lot of respect for him for that.”
