The PM also said people who could not work from home – including those in the manufacturing and construction industries – should return to the workplace from Monday but avoid public transport.
Mr Johnson said the government would “modify” lockdown measures over three “careful” steps through to July.
A new Covid Alert System with five levels has been created, which would influence how quickly the lockdown – which was first announced on 23 March – could be changed. Level five is the most critical, and the UK is currently ready to move from level four to three.
The first step will allow people to take unlimited amounts of outdoor exercise, sit or sunbathe in parks and play sports with household members from Wednesday.
The changes in guidelines will also allow two people from different households to meet in a park if they stay two metres apart.
He hoped by the second step – “at the earliest by 1 June” – there could be a phased reopening of shops and some primary aged pupils could return to school.
The third step could see some hospitality businesses and other public places reopen – “if the numbers support it” – but not earlier than 1 July.
The prime minister stressed this was all “conditional” on a series of “big ifs” and he would not hesitate to “put on the brakes” if there are further outbreaks of the virus.
Mr Johnson is set to give a statement to Parliament at 15:30 BST on Monday, with more information expected on a Covid-19 alert system, use of face masks, and the return of professional football. He will take the questions from the public in the evening.
But Sir Keir said Mr Johnson’s speech raised “as many questions as it answers”.
