Right what's the best ways to cut weight
And what's the most you can cut

Iv been told this is a good routine to cut weight

20 min Epsom salt bath then dry off sweat suit on then
10-15 mins of dancing about shadowing skipping
Then a hot shower then another 10-15 mins of dancing about

Iv been offered a semi pro boxing bout an we weigh in the night before
The weight class is 54kg flyweight an I'm gonna cut from 61kg does that seem safe ?
