There are many tools you can use at home that are not bulky/expensive to acquire! Gone are the days where those excuses applied.
Here are some suggestions you may want to consider for your home workouts;
TRX equipment. Their website now also offers free tutorials on how to use it and workout suggestions.
P90x Pull up bar.
** I bought mine on Ebay for $10 as it was collecting dust in someone else’s home. Check similar sites for equipment others have to offer that are still new!!

So inexpensive and provide wonderful resistance to aid you in your strength development.
