Winger Rohan Ricketts has said he would consider a move to Stevenage after talks with Southend fell through.
But he admitted he would have to adapt to Boro boss Graham Westley's heavy training regime.
The 28-year-old, who looked close to agreeing a deal with the Shrimpers, played in Stevenage's 1-0 friendly defeat by an Arsenal XI on Saturday.
"If he gave me the chance to play, I'd definitely consider it," he told BBC Three Counties Radio.
"But it is different. It was like a shock to my body.
"I take my hat off to Graham Westley after winning back-to-back promotions, but the philosophy is completely alien, we were training nine until five.
"We worked hard on Thursday and Friday and had to play Arsenal on Saturday, and they don't lose the ball so I was chasing the ball and didn't get a chance to express myself.
"I'll speak to Graham to see where it goes."
The former Tottenham, Wolves and Barnsley attacker played the first 45 minutes against the Gunners.
Westley told the club website: "We had a look at Rohan for a couple of days, he trained with us Thursday and Friday.
"I think by his own admission he would point to his current fitness level as needing to be worked upon.
"We'll see where that one goes from here on in."
After two weeks of discussions with Southend, Ricketts said the two parties failed to agree on a deal.
"Paul Sturrock said 'I want you, I hope we can agree figures', but then they said they could stretch [to a contract], then they said they can't and it was just dragging," he explained.
