Just to caveat this, you need to be aware of how the trophy number for your clan is determined, because in a sense if there's a few folks in your clan that don't want to push, it's not a big deal if they're lower on the clan roster.
Copied from the Clash WIKI:
Clan Ranking
The clan ranking is based on the number of trophies of its members. This value is weighted according to the following table.
Rank in Clan (Members) % of Trophies that Count Towards Score 1-10 50% 11-20 25% 21-30 12% 31-40 10% 41-50 3%
As you can see from this, it's really the players in your 1-20 spots that account for the majority of your clan trophy count, so if you have 10 or so people that don't want to push then so long as their in that 41-50 range at the bottom of your clan roster then you aren't losing out too much since their trophies will only account for 3% of the overall clan ranking. Hope this helps.
