For anyone who cannot find time for gym or can't afford it there is an at home workout playlist in youtube from Anabolic aliens.They are effective. I have tried them. They have workouts for each body group. But i would personally recommend to go for only biceps, triceps, abs, forearm, legs and calf if you are a beginner.

For Biceps For triceps For chest Upper abs Middle abs Lower abs Leg Calf Forearms

Start with 1 set [The whole 5 min workout= 1 set] After 2 weeks, you can go for 2 sets.

Recommended routine:

Sunday/Wednesday- Biceps, Upper abs, Legs Monday/Thrusday- Chest, middle abs,forearms Tuesday/Friday- Triceps, lower abs, calf Saturay= Rest day

The time for total workout is about 30 minutes[If you do 1 set each] so don't give your lazy ass excuses.
