Lazy start - sweethearts turn over and don't get up (5,2)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

We think this must be: L (first letter or ‘start’ of lazy) E (the middle letter or ‘heart’ of ‘sweet’) E (repeated as ‘sweethearts’ is plural) with SPIN (turn) outside or ‘over’ – we’re not convinced by the wordplay for repeating the ‘e’ though but maybe we are reading it wrongly.
