Another exercise that is fairly new to me, as well as being something that is ideal for an At Home workout is the medball situp.
Great for the Core and Abs. Also a solid conditioning exercise for wheelers as you are working a ton of body parts in a repetitive manner. Amazing for any kind of MetCon workout. If you don’t have a medball, a dumbell can be substituted or a kettlebell or even a backpack loaded with some books for weight.
