Hello, I'm trying to lose weight and want to tone up for an upcoming family function after 5 months. I have lost weight earlier in the past and have the will power to do it. Even now I'm in the correct weight range.. I want to tone up , infact. I'm in early 40 now so this is not happening as I want it to be. Right now I'm doing once a week zumba and walk 45 mins other 5 days (one rest day)Please suggest if I should be doing strength training too and what's the best combination I should be following to see results. Has anyone been able to achieve this ? Please share.
