You can't go to the gym is not an excuse. Let me give you a few exercises you can do in your house without using any equipment.
Push ups
Jumping jacks
Burpees
Bodyweight squats
Diamond push ups
Jump squats
Lunges

These are just a few. So no excuses guys. Try it first thing in the morning or immediately you come back from work.

Tell them from now till tomorrow they will never do. The only exercise most Nigerians love doing is creating excuses to not put in work.

I do these and know they work. It’s funny because I started with the weight lifting-thing like every other male. My original aim was trying to put on weight. I came to the conclusion of bodyweight workouts when I realized conventional weights will not stay steadily accessible in the real world.

Bodyweight workout are a good way to start up a strength training program to gain weight, but to get a substantial growth in muscles you have to constantly progress in reps and loads which entails that eventually you might need to throw in some weight.
