A gruelling Jamie Heaslip measure to lose weight looks like torture

These are the measures taken.

Leinster got their PRO14 campaign off to a flying start, when a youthful side condemned Bernard Jackman's Dragons to a 39-16 defeat in Wales last weekend. Leo Cullen's side will make their first home appearance of the season on Friday evening at 7:30, when they take on the Cardiff Blues in the RDS, and they will be looking to build on last week's strong showing. Leinster are hot favourites for the game, which will be broadcast on TG4, and are priced at 1/12 with most bookmakers. Sportsfile were granted access to a Leinster training session on Wednesday, and the lads were keeping themselves in prime-order, undertaking all kinds of exercises in their squad gym in UCD. Cian Healy was in business-mode as he performed his squatting routine. Rob Kearney was focusing on his speed exercises, with plyometrics and bounding the theme of the day. Sean O'Brien was testing his flexibility range to the limit, with his use of speed bands. Devin Toner may be 6 ft 9 in tall, but that doesn't deter him from his 'ass to the grass' squatting routine. Serious work from Devin. Johnny Sexton's chest was bulging out of that training top with his intense Dumbbell Bench Press routine. Jamie Heaslip didn't appear in Sportsfile's collection of gym photos, but the 33-year-old took to Instagram to showcase the gruelling measures he is taking as he makes his return from the first serious injury of his career, which caused him to miss Ireland's Six Nations campaign. The Number 8 was doing the hard yards in the Sauna on Thursday to ensure he's lean and ready to go when called back into action for the blues. Indeed, this sauna work has been a theme of his summer, and an update from almost a month ago revealed that he was spending 40 minutes straight in the heat-room. Grueeling, gruelling stuff. The lads met up in the team canteen to ensure the tank was refuelled soon after. No stone left unturned.
