To get in shape, I advise you to do cardio or buy simple home sports equipment .
If you want to lose weight , the best option is cardio , especially running - it burns the most calories. You can even run every day. But it's worth starting with jogging 3 times a week. The first workouts can be very short - 10-15 minutes, but gradually it is necessary to increase the duration of classes, up to 40-60 minutes.
If you want to acquire a beautiful muscle relief , it is worth purchase dumbbells . I would advise taking typesetting so that you can change the weight depending on the exercise, as well as increase the load over time.
With the help of dumbbells, you can pump all the muscles. Exercise 3 times a week. If you want to lose some weight and tighten muscles, do many reps (more than 15 in each set) with light weights. If the goal is to build muscle mass, do exercises with heavy weights, you should have enough strength to do only 6-12 repetitions.
Nutrition should also be reviewed , exclude unhealthy high-calorie foods (mayonnaise, fried, starchy foods, sugary soda, etc.), and adding more protein will help build muscle.
make a variation of the crossfit cindy complex:
workout lasts 20 minutes
consists of three exercises, doing all three is one set
break between sets is either absent or minimal
20 sit-ups (lifting the torso from a prone position, not twisting, but a full lift until touching the floor next to / between the feet, in front of you)
this is a home option, in the original there are 5 pull-ups instead of sit-ups, but not every home has a bar.
Try to run at a calm pace for 30-45 minutes a couple of times a week and / or Interval (run fast for a minute (as you can), practically walk for one and a half, so 15 minutes)
Practice regularly! Make a schedule for yourself 3-5 times a week, not skipping to do basic exercises, such as: Push-ups, pull-ups, abs, back (lying) and everything, this is enough to keep fit. The main thing is regularity.
