England face a series of high-profile assignments in the coming months, with the visit of New Zealand followed by a home Champions Trophy and the eagerly-awaited Ashes.
Broad, who has been cleared to play in two LV= County Championship matches for Nottinghamshire, starting against Derbyshire on April 24, told Sky Sports News: "I haven't played a lot of county cricket for the last couple of years but I'm really looking forward to getting in shape for what is a really big eight months ahead of us."
He added: "I've had two weeks off the feet and now it's a real intense lift for the county season, a few games for Notts and then hopefully into the international summer.
"I start at Derbyshire in about 10 days' time and I'm really looking forward to helping Notts get off to a good start.
"April has been good to use as a bit of a fitness month before the season gets into full swing.
"We (England) had a couple of niggles over the winter but the guys seem to be coming back to full fitness for what is such an exciting time for an England cricketer."
