As a beginner, what should my workout schedule be at a gym?

Hello,
In the past I had written an article in my blog, addressing this topic. I welcome you to go ahead and read it.
Workouts 101 - First time at a gym? Read this..

Also here, where I had listed a good conditioning workout - suitable for beginners. Getting back into shape!

Here's the workout schedule for your benefit. Workout A is a conditioning program recommended for 3-4 weeks, after which you can move to workout B.
Note: When I put this program together, I was recovering from injury, and focused on exercises that did not necessarily require a fully equipped GYM.

Workout A: Conditioning (I did this for about 2 weeks)
MON-WED-FRI: (estimated time 20 minutes – excluding the walk)
  1. Brisk walk in the outdoors (30 minutes) ‘optional – but recommended'
  2. Basic full body stretching (5 minutes.)
  3. Floor Push-Ups (10 x 3 sets)
  4. Plank (3 sets x 15 seconds)
TUE-THU-SAT: (estimated time 20 minutes – excluding the walk)
  1. Brisk Walk in the outdoors (30 minutes) ‘optional – but recommended'
  2. Basic Full Body stretching (5 minutes)
  3. Free Squats (15 x 3 sets)
  4. Plank (3 sets x 15 seconds)
SUNDAY:-REST
Workout B: Full Workout
MON-WED-FRI: (estimated time 25 minutes – excluding the walk)
  1. Brisk Walk in the outdoors (30 minutes) ‘optional – but recommended'
  2. Basic Full Body stretching (5 minutes)
  3. Free Squats (20-25-20-15)
  4. Hamstring Curls* (20 x 3 sets)
  5. Standing Calf Raises (25 x 2 sets)
  6. Plank (30 seconds x 4 sets)
  7. Side Plank (15 seconds x 2 sets)
*Hamstring Curls: Normally this is done on a leg extension/curl machine in the gym. But there is an easy home based alternative too. Here's How:
  • Lie face down, on your stomach, on a thick mat or a blanket (ensure that your knees are not touching the hard surface of the floor directly – this may lead to an avoidable injury).
  • Lift your upper body such that you are resting on your elbows (imagine lying down on a beach, on your stomach)
  • Now bend your knees, bringing your heels towards your buttocks (ensure that your feet are together in this motion) as far as you can – exhale.
  • Slowly bring it back to starting position – inhale.
  • You don't have to touch the toes back to the floor. Try to keep them in the air.
  • I have recently purchased a pair of 1 kg ankle weights, for extra resistance. But this is optional.
TUE-THU-SAT: (estimated time 30 minutes – excluding the walk)
  1. Brisk Walk in the outdoors (30 minutes) ‘optional – but recommended'
  2. Basic Full Body stretching (5 minutes)
  3. Floor Push-ups (I recommend following the schedule as per the 100 push ups challenge website – read the site carefully and choose your routine, depending on your current level)
  4. Biceps Concentration Curls ("optional" 15 X 2 sets)
  5. Tricep extension ("optional" 10 x 2 sets)
  6. Plank (30 seconds x 4 sets)
  7. Side Plank (15 seconds x 2 sets)
SUNDAY:-REST

What are the disadvatages of crossfit training?

(I like to train. I have been a competitive runner and triathlete, a former military diver, and a regular CrossFit gym client for 3.5 years, and have been coached by roughly a dozen different trainers in that time frame. I have completed the CrossFit L1 Trainer course but I don't actively coach any clients.)

When/how should I approach squatting? I last squatted a few months ago. The next day my lower back was locked/in pain likely due to lack of mobility and/or I squatted too much weight too soon. I started stretching/gym routine again, but no squats.

Squatting is a tricky exercise as it activates multiple muscle groups, which have a tendancy to get very tight on most people. If you were feeling pain the next day there could be a whole slew of reasons why. Beyond that, I've always taken the approach that squatting should
