Gloucester's players returned to pre-season training on Monday with the likes of Phil Vickery, Ludovic Mercier and Andy Hazell all going through the first sessions.
Fitness and conditioning coach Mike Anthony took the opening session at 8am on Monday morning with the forwards, followed by the backs starting work at 9am.
The majority of the squad returned to pre-season training including new signings Ludovic Mercier and Patrice Collazo.
The likes of James Simpson-Daniel, James Forrester and Peter Richards will return at a later date after completing Churchill Cup duties with England at the weekend.
As the Gloucester squad kicked off the early season fitness work, there are a number of players who have been working non-stop all summer to get themselves back after injuries picked up last season.
Henry Paul injured his medial ligament in his knee last season and missed the final few weeks. The international centre has been continuing with his rehabilitation throughout May and June, and is on track for joining in pre-season this week.
Andy Hazell also missed the final few weeks of the season after a knock to the head against London Irish at the end of March. The England open-side is also set to start pre-season this week.
Phil Vickery broke his arm against Bath in February and was ruled out of the remainder of Gloucester's season, including the Lions tour to New Zealand. The 29 year-old prop has been maintaining his fitness levels, and was one of the first at the training ground for the 8am start on Monday.
Mike Tindall joined Gloucester this summer from Bath. He underwent an operation on a shoulder injury earlier in the year and is progressing well, having been meeting with the Club's physio team throughout the summer. The England centre is currently on target for a return to full match duties in August.
Mefin Davies will return to pre-season slightly later after a busy summer spent touring with Wales. The Grand Slam winning hooker had a small back problem whilst he was touring with the Welsh national side, but it's cleared up and he should be returning to pre-season soon.
Marcel Garvey had a standard procedure sports hernia operation at the end of the season, and was lining up with the likes of Jon Goodridge, Mark Foster and some of the new signings including Haydn Thomas on Monday.
Simon Amor has been receiving treatment for a slight hamstring problem, that ruled him out of England's Sevens tournament in Paris recently. The half-back will continue to work with the physio team.
James Merriman has undergone an exploratory arthroscopy on the knee injury that ruled him out of Wales' U21s World Cup midway through the tournament.
The young Welsh flanker missed most of last season after a knee ligament injury, but has been told that the recent knock is not as serious as last season.
Merriman will be given the chance to recover before hopefully making the trip to France for the Issoire tournament at the end of July.
With such a short turnaround between the two games, and Gloucester looking to reintegrate several players into the line-up after the Autumn international series, Tom Savage told GRTV that the Cherry and Whites will keep changes to a minimum for the European Rugby Challenge Cup game in Zebre on Saturday.
Gloucester travel to Italy this weekend to take on Zebre in Round Four of the European Rugby Challenge Cup. The Cherry and Whites defeated the Italian side 35-10 last Sunday, but Director of Rugby David Humphreys is looking for an improved performance in the return fixture.
Skipper Billy Twelvetrees, speaking to GRTV after the 35-10 over Zebre, was happy with the bonus point win over the Italian side but admitted Gloucester will need to tighten up for the return fixture in Parma.
Matt Kvesic was a try scorer and recipient of the Man of the Match award in Sunday's 35-10 European Rugby Challenge Cup win over Zebre. He praised the Italian side for their spirited opposition and admitted that next week's return game will be a tough one.
