Hi Dear

Save your pennies, you don't need to go to Gym or buy any equipment.
Do Push ups, Pull ups, Dips, Squats narrow and sumo. For warm up you can do some walking or Jogging and for cool down you can do some stretches and bending.
Don't spend any thing on suppliments. Have a Balanced Diet rich in Proteins.
Have a Good 8 hrs Sleep.

Hiya Jose
As a beginner your aim should be to establish correct technique whilst lifting a suitable weight. The weight you need to lift, will be as much as is comfortable for the reps outlined, with the last 2 - 3 reps becoming hard but not impossible to lift.

For best results you will want to train with weights 2 - 3 times per week for about 30 - 45 minutes, working on 2 or 3 different muscle groups for each workout. Combining C.V. (aerobic exercise) training with your weight training will help develop correct muscle tone, and also a reduction in body fat.

Adjust your weights gradually, once you can lift the set number of reps comfortable, take the weight up slightly, bearing in mind that you may not be able to still do the same number of reps as before.

Stop immediately if you feel any pain or discomfort whilst lifting, do not work to failure, rest when you need to, either between each exercise for ideally 30 seconds to 2 minutes, and between training sessions. Aim to train with a minimum of a days rest between sessions.

Setting goals is a good way to stay motivated, however make sure that they realistic, too many people quit training, as they don't see any results. Results take time, and because they are gradual are often hard to see for yourself. Taking photo's or simple body measurements is a good idea, so that you can monitor your progress every 6 -8 weeks.
Hope this helps
