I am trying to reduce years of weight training muscle bulk. Suggestions on a leaner muscle?

Taught aerobics for 11 years and stopped about 10 years ago because of car wreck. Neck problems. Cannot do impact cardio. I am trying to reduce muscle mass and become leaner looking. I need to lose 15 to 20 pounds. Currently watching diet 6 meals a day no more than 1200 or 1500 cals. Cardio an hour a day 5 days and 3 days of weight training high reps low weights. I have been doing this for about 3 weeks. Noticed a small change in clothes fitting loser but want results in 7 weeks that look amazing. Shooting for my birthday. I am 40 so 41 I want to look better. I am 5′7″ weighing in at 156 would love to be 135 to 140. Any suggestions?

Theres no quick way to loose muscle mass. What your doing is about the best you can do to loose muscle mass. But, i have a question…..sounds to me that your already fit and look amazing. Especially at 40. Be yourself and your amazing personality will shine more than your amazing body. If anyone tells you otherwise then there nuts.
