Do purchase the pullup bar – probably the best home gym equipment you can purchase. Also, while there may not be a pullup bar, specifically, nearby – there may be a tree branch, a tall deck, a swing set, or roof rafters that can be used instead. It’s always a good idea just to take a look around and see what can be used – you may be surprised.

There are plenty of exercises you can substitute, but it should largely depend on your goals. Bodyweight rows can be performed on the edge of a sturdy table, or even two sturdy chairs. This would be my first general recommendation, but there are others:

1. dumbbell rows
2. barbell rows
3. odd object rows, such as with sandbags, bands, or stones.

It really depends on what you have available to you.

Thanks for the note, Matt.

Mountain climbers – place your hands in a pushup position on the ground in front of you, at about shoulder width apart. Place one foot extended out behind you (like a pushup position, only using one leg). The other leg should be bent at the knee, with your thigh up near your belly.

This is the start position, with your hands planted and your feet straddled. To execute the movement, kip your rear foot up to your belly, and your “lead” foot backwards (essentially switching positions). This should be repeated for reps – anywhere from 10-50 is good depending on your goals.
