Went to the gym. Had a scattergun aproach! Help!

[upahill]

I used to be really fit and toned.
Now I'm not. In fact I'm about 3 stone over weight.
I am fairly fit -eg I've got goos stamina for mountain biking and hill walking but I am fat.
I've been to the gym and it was all a bit random.

I did some kettleball squats and up right rows. I bench presses. I did 2 x 40 seconds of the plank, some powerplate lunges and squats and a few Russian twists.

But I feel a bit disjointed and like I said in the title that I've jumped about and not achieved much.

Any advice on how I can improve please.

I think at the start good to do decent amount of cardio for fat burning, eg work up to a 15 - 20 min run plus 15-20 mins on elliptical trainer/bike.

Then plan weights, choose something for each muscle group - eg
legs - kettlebell squats and powerplate lunges
abs - plank and russian twists
chest - bench press
bicep & shoulders - I like to do reps of 15 with 2kg of front raises, side raises, upright row, shoulder press, bicep curls
triceps - some dips and kickbacks?

I think a PT maybe a good idea to begin with!!
I used to do lots of classes and gym stuff after the babies were born and kept in really good shape up unttil about 2 1/2 years ago.
it's like I'm a beginner all over again!!

Well I was a bit more organized today.
60 mins hard cv stuff.
Then some barbell squats, barbell lunges, kettlebell row, floor kettlebell press and a couple of mins of squats on the power plate.

That was quite enough for one day.

Tomorrow I intend to do 60mins cv and a zumba class!

I feel a bit more organized now!!
