Today I did 120 press ups, 100 sit ups, stomach crunches, dumbell curls.
Just out of curiosity, why did you do that?
i wish, we're strapped for space as it is. Sharing a 2 b/r apartment with a japanes couple on top of a city building reduces my options significantly. actually i might could swing some metal on my balcony, but yeah the machine aint mine to sell, it's part of the building i rent in.
the best i could hope for right, being so strapped for cash, is a long shot hope to maintain my recent gains by using my dumbells with the bodypump class videos i've sourced online and some punching bag stuff.
That's pretty crazy how cramped you must be! 4 people renting a 2 bed apt.....still, living the city life and that, brap brap brap.
You could maintain all of your gains with dumbbells and weighted bodyweight exercises.
Pullups/chinups and pushups, when weighted, effectively work as squats for your upper body and a kind of bench press substitute (but much more effective, imo),
respectively. Both fantastic, imperative lifts. There are a million and one variations of the pushup.
You could also do bent rows (one-arm or both), DB fly's (the best chest exercise, without a doubt), DB press, Shoulder press, one-arm tricep extension, hammer curls, lateral raise and you could even do DB squats.
In effect, you could pretty much do all you would ever need to do with DB's, bar squats and deads of course, but you could do DB deads and DB squats.
So long as you have the DB 's that you add weights to, of course. Get them!
